Answer:
C. the function f(x) has the greater y-intercept by 72 units
Step-by-step explanation:
find f(x) y-intercept:

the y-intercept of g(x) is 3
to find the difference subtract 3 from 75 and you get 72
Step-by-step explanation:
soln;
given; p(x) = x^4 - 3x^3 - 6x^2 + 9
using remainder theorem;
p(x) = p(a)
= p(2)
= (2)^4 - 3(2)^3 - 6(2)^2 + 9
= -23
