Answer:
Step-by-step explanation:
(g-f)(x) = 9x³ - 4x² + 10x - 55 - [ 4x³ +3x² - 5x + 20]
To remove the parenthesis, take - inside, multiply f(x) by -1
= 9x³ - 4x² + 10x - 55 - 4x³ - 3x² + 5x - 20
Now, bring like terms together,
= 9x³ - 4x³ - 4x² - 3x² + 10x + 5x - 55 - 20
= 5x³ - 7x² + 15x - 75
A reasonable estimate is like 8 or 9 or maybe even 10
hope this helps
F(-11/5) if f(n) = 5n + 6.
f (-11/5) = 5 (-11/5) + 6
f (-11/5) = -11 + 6
f(-11/5) = -5 :)
I don't see the choices.
It is equivalent to 0.8r.
