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

B) y = x2 - 3

Step-by-step explanation:

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

Shift up a units:

Shift down a units:

Shift left a units:

Shift right a units:

So the correct answer for this question is:

B) y = x2 - 3

s

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
