Answer:
f(-1) = -3
Step-by-step explanation:
(Assuming {2} is ^2)
f(-1) = 3(-1)² + 4(-1) - 2
= 3(1) - 4 - 2 = -3
Step-by-step explanation:
The table of three and x is common
So
3x ( x + 5)
Is the answer
Answer:
f(g(x)) = 8x² + 18x - 8
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(- 2x - 1)
= 2(- 2x - 1)² - 5(- 2x - 1) - 15
= 2(4x² + 4x + 1) + 10x + 5 - 15
= 8x² + 8x + 2 + 10x - 10
= 8x² + 18x - 8
