If f(x) = 2x - 6 and g(x) = x^3, what is (gºf)(6)?
enter the correct answer.

NOTE: (gºf)(6) means g(f(6)).

First find f(6).

f(6) = 2(6) - 6

f(6) = 12 - 6 or 6.

We now find g(6).

g(6) = (6)^3

g(6) = 216

ANSWER:

(gºf)(6) = 216

536

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
