By comparing equation
a=2,
x-h=x+1, -h=1, h=-1
k=-3
h=-1 move graph to the left (because h=-1 is negative) by 1 unit, h is moving to the left or to the right(horizontal shift)
a=2 vertical streaching
k=-3, k shows vertical shift , k=-3 moving 3 units down because it is negative
Answer:
A
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
f(x) - g(x)
= 2x² + 2 - (x² - 1) ← distribute
= 2x² + 2 - x² + 1 ← collect like terms
= x² + 3 → A
