Question

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

Explanation:

Step1: Set x=0 for y-intercept

Substitute $x=0$ into $f(x)$.
$f(0) = -8 + (0)^4$

Step2: Simplify the expression

Calculate the value of the function.
$f(0) = -8 + 0 = -8$

Answer:

$-8$
