HURRY! Will Give Brainliest! Which of the following graphs could be the graph of the function f(x) = x^4 + x^3 -x^2 -x

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

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
