1-203.

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

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

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

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

4. $g(x) = \log_2(x - 1)$

5. $g(x) = \log_2(1 - x)$

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 $f(x)...$
