Question

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

Answer 1

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)

Answer 2

Answer:

The y-intercept of the given function is 0.

Step-by-step 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.
