question
what is the y-intercept of the polynomial f(x) defined below? write the y-value only.
f(x) = -8 + x^4
answer attempt 2 out of 2

Explanation:

Step1: Recall y-intercept definition

The y-intercept occurs at $x=0$.

Step2: Substitute $x=0$ into $f(x)$

$f(0) = -8 + (0)^4 = -8 + 0 = -8$

Answer:

-8
