Answer:
20.
Step-by-step explanation:
When x = 2
f(x= 3(2)^3 + 2^2 - 8
= 24 + 4 - 8
= 20.
6/8-3/8
3/8
the answer to 3/4-3/8 is 3/8
Answer:
the second
Step-by-step explanation:
f(x) = 1 - ²/ₓ₃
y = 1 - ²/ₓ₃
y = 1 - ²/ₓ₃
y - 1 = ⁻²/ₓ₃
x - 1 = -2/y³
y³(x - 1) = -2
y³ = ⁻²/ₓ₋₁
y = ∛⁻²/ₓ₋₁
y = -∛(2x² - 4x + 2)/x - 1
f⁻¹(x) = -∛(2x² - 4x + 2)/x - 1
