Question

Chelsea is graphing the function f(x) = 20(One-fourth)x. She begins by plotting the initial value. Which graph represents her first step?

On a coordinate plane, the point (0, 0.25) is graphed.
On a coordinate plane, the point (0.25, 0) is graphed.
On a coordinate plane, the point (0, 20) is graphed.
On a coordinate plane, the point (20, 0) is graphed.

Answer 1

The initial value is f(0). If f(x) = 20*(1/4)^x, then f(0) = 20*(1/4)^0 = 20. So she should plot (0, 20).
