Question

Let f(x) = x + 6 and g(x) = x – 5. What is f(x) • g(x)?
Answer:
A) x2 – 6x + 1
B) x2 – x + 30
C) x2 + 6x + 30
D) x2 + x – 30
help me please?:)

Answer 1

f(x)*g(x)


(x+6)(x-5)


x^2-5x+6x-30


x^2+x-30


So the answer is choice D

Answer 2

Yay! thank you!
What about this one?

Answer:
A) x + 4
B) 3x + 2
C) 2x + 2
D) 2x + 1
:)))

Answer 3

f(x) = x-1


f(g(x)) = g(x)-1


f(g(x)) = (2x+3) - 1


f(g(x)) = 2x + 2


so choice C
