Which of the following functions has a graph with a vertex that is a translation 5 units horizontally to the right of the vertex

andrezito [222]

Answer:

g(x) = (x -3 )^2 + 2

Step-by-step explanation:

f(x) = (x + 2)^2 + 2

We want to shift this 5 units to the right

The parabola is written in the form

y = a(x-h) ^2 +k where (h,k) is the vertex

The vertex is at ( -2, 2)

We want to shift it 5 units to the right

-2+5 = 3

g(x) = (x -3 )^2 + 2

Leni [432]

Answer:

$5.39

Step-by-step explanation:

In order to solve for this equation, we are going to multiply 7.70 by 0.3 to find how much money was taken which was 2.31.

Subtract2.31 from 7.70 to recieve your new price :)

$7.70*0.3=2.31\\7.70-2.31=5.39$

Hope this Helps!
