1-203.

Multiple Choice: When the graph of $f(x) = 1 − 2^x$ is reflected across the $y$-axis, the resulting graph is:

1. $g(x) = 1 - 0.5^x$

1. $g(x) = 1 + 2^x$

1. $g(x) = 2^x - 1$

1. $g(x) =\text{log}_2(x - 1)$

1. $g(x) =\text{log}_2(1 - x)$

Reflective symmetry across the $y$-axis means that $f(x)$ is an even function. The definition of even functions is $f(x) = f(-x)$.

Evaluate $f(-x)$...
