Answer:
(f-g)(x)= -2x
(f.g)(x)= 3x^2 + 8x +4
(f+g)(-1)=0
Explanation:
Given:
f(x) = x + 2
g(x) = 3x + 2
(f-g)(x)=?
(f.g)(x)=?
(f+g)(-1)=?
The expression for (f-g)(x) is:
(f(x)-g(x))(x) = (x + 2) - (3x + 2)
=x+2-3x-2
Simplify
(f(x)-g(x))(x) = -2x
The expression for (f.g)(x) is:
And, the evaluation for (f+g)(-1) is:
(f(x) +g(x))(-1) = ((x + 2)+(3x + 2))(-1)
This means we let x= -1.
We plug in what we know:
=x + 2+3x + 2)
=-1+2+3(-1)+2
Simplify:
=-1+2-3+2
=-4+4
(f(x) +g(x))(-1) = 0

Answer:
Your answer should be 647.51
Explanation : the price was 215.949 in December, 2009.
the price was 233.049 in December, 2013.
divide 233.049 by 235.949 and got 1.079185363.
multiply that by 600 and got 647.5112179.
-4x^2-5(x+3)+x^2
First, combine like terms.
-4x^2+x^2= -3x^2
-3x^2-5(x+3)
Distribute the 5.
-3x^2-5x-15 <=== the simplified answer
I hope this helps!
