Answer:
(0, -22)
Step-by-step explanation:
The y-intercept is the value of y when x is 0,
f(x) = -x² + 10x - 22
f(0) = -(0)² + 10(0) - 22
f(0) = - 22
The y-intercept is -22 at point (0, -22).
-> We can also see this when graphing, please see attached.
Note: If you want me to solve for f(x) = -x² + 10x - 12 as you wrote in text and not f(x) = -x² + 10x - 22 as the picture shows, let me know.
