Question 1186984: Directions: Perform the indication operation in the following functions. Show your solution. Write your answer at the back.
I. Given the functions f(x) = 3x + 4 and g(x) = 3x², find:
1. (f + g)(-3)
2. (f - g)(2)
3. (f - g)(x)
II. Given f(x) = x²+ 1, g(x) = 2 - x and q(x) = 1/x²+4x-3, find:
4. (q - g)(-1)
5. (fg/q)(2)
6. (f + g)(x)

Perform the indication operation in the following functions. Show your solution.
-----------
Write your answer at the back.
----
At the back of what?
========================
I. Given the functions f(x) = 3x + 4 and g(x) = 3x², find:
1. (f + g)(-3)
Find f(-3) and g(-3), then add them.
======================
2. (f-g)(2)
Similar to 1.
===============
3. (f-g)(x)
Subtract
============
II. Given f(x) = x²+ 1, g(x) = 2 - x and q(x) = 1/x²+4x-3,
Is q(x) 1%2Fx%5E2+%2B+4x+-+3?
Or 1%2F%28x%5E2+%2B+4x+-+3%29?
find:
4. (q - g)(-1)
5. (fg/q)(2)
6. (f + g)(x)
