Match each equation with the graph of f, g, m, or n in the figure.
(A) y = (0.2)^x (B) y = 2^x
(C) y = (1/3)^x (D) y = 4^x

(A)
(B)
(C)
(D)
if all given functions will be ; so, all of them have same y-intercept and it is
since
(A) => =>=>, have graph at II quadrant
and (C) =>=>, they have graph at II quadrant
so, A and C could be only and
since is closer to then , means it growth is "bigger" and "faster" then ; so, we can say
is then
is
in I quadrant we have B and D, evidently D is growing "bigger" and "faster" then B, so
is
is
