Answer:
y = 3x² - 6x - 72
Step-by-step explanation:
Since the roots are x = - 4 and x = 6 then the factors are
(x + 4) and (x - 6) and the quadratic function is
y = a(x + 4)(x - 6) ← a is a multiplier, in this case 3, so
y = 3(x + 4)(x - 6) ← expand factors and distribute by 3
y = 3(x² - 2x - 24)
y = 3x² - 6x - 72
F(x)= -6(-1)+9
F(x)= 6+9
The answer is 15
