Domain And Range Of A Function F X
Find the domain of function f defined by.
Domain and range of a function f x. Put any number into the sin function in your calculator. If x is a real number x 2 is either positive or zero. The function equation may be quadratic a fraction or contain roots.
As a function table and as a set of coordinates. To calculate the domain of the function you must first evaluate the terms within the equation. The range of a function is all the possible values of the dependent variable y.

Any number should work and will give you a final answer between 1 and 1 from the calculator experiment and from observing the curve we can see the range is y betweeen 1 and 1.
F x x 2 1. The example below shows two different ways that a function can be represented. Hence we can write the following.
Solution to example 4. The domain of the function is all of the x values horizontal axis that will give you a valid y value output. The range is the set of values that f x takes as x varies.
A quadratic function has the form ax 2 bx c. X 2 0. The absolute value expression has a v shape.
