Question

What is the y-intercept of the function f(x) = –x ?

Answer 1

The y-intercept of the given function is 0.

Explanation:

We have been given function
`f(x)=-x`. We are asked to find the y-intercept of our given function.

We know that y-intercept represents initial value of function that is at
`x=0`.

To find y-intercept of our given function, we will substitute
`x=0` in our given function.

`f(0)=-0`

`f(0)=0`

Therefore, the y-intercept of our given function is 0 that is at origin.

Answer 2

The y-intercept is the value of a function when x = 0.

Therefore, when x = 0,
f(x) = 0

Therefore, y-intercept is (0, 0)
