Question

Identify the exponential function for this graph. (be sure to look at the scales on the x-axis and y-axis

A-f(x)=2•(4)^x
B-f(x)=4•(0.25)^x
C.f(x)=2•(0.25)^x
D.f(x)=0.25•(2)^x​

Answer 1

Answer: C.f(x)=2•(0.25)^x

Step-by-step explanation: took the quiz

Answer 2

C

Explanation:

Since the y-int. is 2 we know that the coefficient of the exponential term is 2, which eliminates B and D. Since f(x) decreases from left to right, the number in the parentheses has to be less than 1, so the answer is f(x) = 2 * (0.25)^x.
