Answer:
f(2) = -40
Step-by-step explanation:
Just substitute x=2 into the function:
f(x) = 2x³ - 3x² - 18x - 8
f(2) = 2(2)³ - 3(2)² - 18(2) - 8
f(2) = 2(8) - 3(4) - 36 - 8
f(2) = 16 - 12 - 44
f(2) = 4 - 44
f(2) = -40
I think the answer is x^4
-2 x 3 +4
-6+4
the answer is -2
then for the second one
5+4 x 6
5+24
answer =29
29/33 is already in simplest fraction form
29 is a prime number and cannot be simplified more
