Question

Can someone explain what to do

Answer 1

Answer:

8

Step-by-step explanation:

The equation of the parabola can be represented as

$y = a(x + 1)(x - 5)$

for some constant a.

Since the coefficient of x² is 2, a = 2, so

$y = 2(x + 1)(x - 5) \\ \\ y = 2( {x}^{2} - 4x + 5) \\ \\ y = 2 {x}^{2} - 8x + 10$

So, the answer is 8.
