Question

find the y-coordinate of the y-intercept of the polynomial function defined below.\\( f(x) = -4 + 4x - 6x^2 \\)

Explanation:

Step1: Recall y-intercept definition

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

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

$f(0) = -4 + 4(0) - 6(0)^2$

Step3: Simplify the expression

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

Answer:

-4
