The correct answer is that the focus is, <u><em>(0,−2)</em></u>
Answer:
1 second
Step-by-step explanation:
y = -16x² + 32x
y = -16(x² - 2x)
y = -16(x² - 2(x)(1) + 1² - 1²)
y = -16(x - 1)² + 16
Max height is when (x-1) = 0
So x = 1
The value of y is -7 because you will add 4 on both sides and adding to negatives is adding and keeping the sign of the larger number.
