Question

Which equation would shift the parabola down 3 units? A) y = x2 B) y = x2 - 3 C) y = x2 + 3 D) y = (x + 3)2

Answer 1

x^2-3

Explanation:

Answer 2

B) y = x2 - 3

Explanation:

Suppose you have a function y = f(x), you can do these following operations on the function:

Shift up a units:
`y = f(x) + a`

Shift down a units:
`y = f(x) - a`

Shift left a units:
`y = f(x + a)`

Shift right a units:
`y = f(x - a)`

So the correct answer for this question is:

B) y = x2 - 3
