Were given a function and we're asked to find the domain and range of dysfunction Function is F of X equals one plus X square Notice that the function F is a polynomial function that's a quadratic function and therefore the domain of F is all real numbersActually, at first glance, I don't know So I have to break this down into parts that I do know tan(x) = sin(x) / cos(x) And I know 1/tan(x) = cos(x)/sin(x), so to find the domain I have to look for the places where the denominator is zero (first114 Range of a function For a function f X → Y the range of f is the set of yvalues such that y = f(x) for some x in X This corresponds to the set of yvalues when we describe a function as a set of ordered pairs (x,y) The function y = √ x has range;
Transcript Misc 6 Let f = {("x, " 𝑥2/(1𝑥2)) x ∈ R } be a function from R into R Determine the range of f f = { ("x , " 𝑥2/(1𝑥2)) x ∈ R } We find different values of 𝑥2/(1 𝑥2) for different values of x Domain Value will always be between 0 & 1 We note that Value of range y = 𝑥2/(1 𝑥2) is always positive Also, it is always between 0 and 1 Hence, Range is 1 Confirm that you have a quadratic function A quadratic function has the form ax 2 bx c f (x) = 2x 2 3x 4 The shape of a quadratic function on a graph is parabola pointing up or down There are different methods to calculating the range of a function depending on the type you are working withAnswer and Explanation 1 Given f(x) = 1 x f ( x) = 1 x Domain Since the function is a fraction, the value of the variable are all real numbers except 0 0 since it will result to an undefined

Domain and Range of Exponential and Logarithmic Functions Recall that the domain of a function is the set of input or x values for which the function is defined, while the range is the set of all the output or y values that the function takes A simple exponential function like f(x) = 2x has as its domain the whole real lineArithmetic Mean Geometric Mean Quadratic Mean Median Mode Order Minimum Maximum Probability MidRange Range Standard Deviation Variance Lower Quartile Upper Quartile Interquartile Range Midhinge Standard Normal Distribution f(x)=\frac{1}{x^2} domain\y=\frac{x}{x^26x8} domain\f(x)=\sqrt{x3} domain\f(x)=\cos(2x5) domain\f(x(1, infinity) , {y/y > 1)
For example, a function f (x) f ( x) that is defined for real values x x in R R has domain R R, and is sometimes said to be "a function over the reals" The set of values to which D D is sent by the function is called the range Informally, if a function is defined on some set, then we call that set the domainThe domain is all real numbers, and the range is all real numbers f(x) such that f(x) ≤ 4 You can check that the vertex is indeed at (1, 4) Since a quadratic function has two mirror image halves, the line of reflection has to be in the middle of two points with the same y value1 find the domain and range of f(x) 2 cos3x close Start your trial now!

The answer for the question shown above is the second one, which is The domain is all real numbers The range is all real numbers greater than zero The explanation is shown below You have the following function given in the problem above f(x)= (1/5)^x As you can see, it is a exponential function The range is the set of all valid values Find the domain and range of f (x)=x2/1x2 Domain of the function is where the function is defined The given function X R Let fx y y x1x2 x y1 x2 yx2 x y 0 This is quadratic equation with real roots Find the domain and range ƒx 1 x2 Maintain the following steps 1 Rangeset of values of f(x)/y for given domain Here f(x)=√(x1) We know that root of negative number is not defined (ideally we can take iota ibut we can not take i without being mentioned) So,our X must be greater or equal to 1 Domain is(1,inf) For range put x= 1 minimum value is 0 and maximum can go upto infinite So,range is (0,inf)
For instance, f(x) = itex\frac{1}{x3}/itex The domain is simply the denominator set equal to 0, {xl x≠3} However, range is found by solving for (isolating x to one side) and setting the denominator equal to zero x = itex3\frac{1}{y}/itex So range is {xl x≠0} This is a systematic method that I assume is the only way to find the range Find the domain and range of the real function f(x) = x/1x^2 ━━━━━━━━━━━━━━━━━━━━━━━━━ ️Given real function is f(x) = x/1x^2 ️1 x^2 ≠ 0 ️x^2 ≠ 1 ️Domain x ∈ R ️Let f(x) = y ️y = x/1x^2 ️⇒ x = y(1 x^2) ️⇒ yx^2 – x y = 0 ️This is quadratic equation with real roots ️(1)^2 – 4(y)(y) ≥ 0 Given that f(x) = 1/√(x 5) Here, it is clear that (x) is real when x – 5 > 0 ⇒ x > 5 Hence, the domain = (5, ∞) Now to find the range put For x ∈ (5, ∞), y ∈ R Hence, the range of f
We know that element inside the square root should be greater than or equal to zero But in this case since square root is in denominator it can't be equal to zero So in this case element inside the square root should be greater than zero ie
