Question

The y-intercept for the function f(x)=-x^+9

Answer 1

$f(0)=9$

y- intercept=9

Explanation

$f(x)=-(x^2)+9$

Step 1

the y-intercept is when the value for x = 0

then, make f(0) to obtain the y-intercept

$\begin{gathered} f(x)=-(x^2)+9 \\ f(0)=-(0^2)+9 \\ f(0)=-0+9 \\ f(0)=9 \\ \end{gathered}$
