Greg made pudding every weekend. The more times he made pudding, the more practice he gained. The time he took to make the same amount of pudding every week decreased with practice. The function below shows the number of hours f(x) Greg took to make pudding after he had made it x times: f(x) = 2(0.8)x Which graph best represents the function? graph of function f of x equals 0.8 multiplied by 2 to the power of x graph of function f of x equals 0.8 to the power of x graph of function f of x equals 2 to the power of x function of f of x equal 2 multiplied by 0.8 to the power of x

well it can't be b or c since we need to include the 2 and the 0.8 parts

f(x) = 2(0.8)^x pay attention to the location of the exponent. this means the x only applies to the 0.8 not the 2

so it is "2 times 0.8 to the power of x" making D the only viable option
