Question

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 + 2x +1?

A.right 1 unit
B.left 1 unit
C.right 2 units
D.left 2 units

Answer 1

Answer: left 1 unit

Explanation:

Edge 2021 also I’m in a big storm right now so if I’m not online in a few days you know why

Answer 2

The vertex of f(x) = x^2 is (0,0)

The vertex of g(x) = x^2 + 2x + 1 = 0 is (-1,0)

Then, translating the f(x) one unit to the left will map (0,0) onto (-1,0).

Answer B: left 1 unit.
