The function f of x is equal to 5 times 1 fifth to the x th power is reflected over the y -axis. Which equations represent the reflected function? Choose two correct answers.

Reflecting a graph across the y-axis means replacing x with −x. This gives f(−x) = 5(1/5)^(−x), which is choice C; since (1/5)^(−x) = 5^x, the same function is also 5·5^x, choice E.
