Rewrite the function f(x)=-4(x-3)^2+16 in the form f(x)=ax^2+bx+c

Answers

Answer 1
Answer:

Answer:

f(x) = - 4x² + 24x - 20

Step-by-step explanation:

Given

f(x) = - 4(x - 3)² + 16 ← expand the factor using FOIL

     = - 4(x² - 6x + 9) + 16 ← distribute parenthesis by - 4

    = - 4x² + 24x - 36 + 16 ← collect like terms

    = - 4x² + 24x - 20

Drawing picture helps.

For A and B, hand are not opposite, so we can check them out:

A: It goes 11, 12, 1, ..., 6 so yes it is greater than a semicircle (aka 180°)

B: It goes 11, 10, 9, ..., 6 so no it is not greater than a semicircle.

For C and D, 2 and 8 are exactly opposite so either way, it will be exactly semicircle, so clearly it's not answer.

Therefore the answer is A.
The answer is A or the first one. A little confusing just think.
