Question

Find g(x), which is a reflection over the y-axis of f(x)= x2 − x
.(1 point)
Responses

g(x) = −x2 + 7x
g(x) = −x2 + 7x

g(x) = 6x2
g(x) = 6x2

g(x) = −x2 + x
g(x) = −x2 + x

g(x) = x2 + x

Answer 1

To find \( g(x) \), which is the reflection of \( f(x) = x^2 - x \) over the y-axis, we need to replace \( x \) with \( -x \) in the function \( f(x) \).

So, we calculate:

\[
g(x) = f(-x) = (-x)^2 - (-x)
\]

Calculating this, we get:

\[
g(x) = x^2 + x
\]

Thus, the correct response is:

\[
g(x) = x^2 + x
\]
