Question

type the correct answer in each box. use numerals instead of words.
what is the y-intercept of this quadratic function?
$f(x) = -x^2 + 10x - 22$
the y-intercept of function $f$ is ( , ).

Explanation:

Step1: Set $x=0$ for y-intercept

To find the y-intercept, substitute $x=0$ into the function.

Step2: Calculate $f(0)$

$$\begin{align*} f(0) &= -(0)^2 + 10(0) - 22\\ &= 0 + 0 - 22\\ &= -22 \end{align*}$$

The y-intercept has an x-value of 0 and the calculated y-value.

Answer:

$(0, -22)$
