P(x)=-4(x-15)2+2
P(x)=7
P(7)=-4(7-15)2+2
-4*7-4*-15
P(7)=-28+60+2+2
P(7)=92
Answer:
Step-by-step explanation:
Given a quadratic equation in the form , you can use the Quadratic formula to solve it. This is:
Then, you need to subtract from both sides of the equation given:
You can identify that:
Then, substituting values into the Quadratic formula, you get:
