Exponential function f is represented by the table.
X = -2 -1 0 1 2
f(x) = -62 -30 -14 -6 -2
Function g is represented by the equation. g(x)=-20(1/2)x+10
Which statement correctly compares the two functions on the interval [-2, 1]?
A. Only function f is increasing, and only function f is negative.
B. Both functions are increasing, but function f increases at a faster average rate.
C. Both functions are increasing, but function g increases at a faster average rate.
D. Only function f is increasing, and both functions are negative.
