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

C

Step-by-step 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.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
