Chelsea is graphing the function f of x is equal to 20 times 1 fourth to the x th power She begins by plotting the initial value. Which graph represents her first step?

The initial value is the function value when x = 0. For f(x) = 20(1/4)^x, f(0) = 20(1/4)^0 = 20 × 1 = 20. So Chelsea’s first point is (0, 20), which is the graph in choice C.
