Question

Which of the following functions shown in the table below could be an exponential function? Check all that apply.

x       -3     -2        -1       0         1                2              3
f(x)  0.37   1.11    0.82     2       3.65          5.15            8.45
g(x) 0.008  0.04    0.2      1          5             25               125
h(x) 1.25   1.5      1.75     2       2.25          2.5                2.75
k(x) 64      16       4         1       0.25        0.0625           0.0156

A. f(x)
B. g(x)
C. h(x)
D. k(x)

Answer 1

 

G(D=5^× Exponential

H (x) = X+2.25 Not Exponential

K(x)=x^-2Exponential
