Answer:
b. g(x)
Step-by-step explanation:
f(x) = (x-13)^4 -2
(x-13)^4 is always positive or zero so the smallest f(x) can be is -2
g(x) = 3x^3 +2
x^3 can get as negative as it wants as x goes to negative infinity this goes to negative infinity
g(x) goes to negative infinity
f(x) min is -2
g(x) min is - infinity
g(x) has the smallest minimum value
