g(x)=2x−1
g left parenthesis x right parenthesis equals 2 x minus 1

g(x)=−2x−1
g left parenthesis x right parenthesis equals negative 2 x minus 1

g(x)=2x+1

Answer 1

To find the function \( g(x) \) based on the rule \( r_{x\text{-axis}} \), we need to reflect the function \( f(x) = -2x + 1 \) across the x-axis.

Reflecting a function across the x-axis is done by multiplying the function by -1. Therefore:

\[ g(x) = -f(x) = -(-2x + 1) = 2x - 1 \]

Thus, the correct function is:

\[ g(x) = 2x - 1 \]

So the response is:

g(x) = 2x - 1
