I would like help making sure that I figured these answers out correctly. If you can show the work, that would help.

PROBLEM ONE: Evaluate each function at the given values of the independent variable & simplify: (I am pretty confident about the a's on each problem, but not as much on the others.)

f (x) = 4x + 5

a) f ( 6) b) f (x + 1) c) f (- x)

PROBLEM TWO: Evaluate each function at the given values of the independent variable & simplify

g(x) = x2 + 2x + 3

a) g(-1) b) g(x+5) c) g(-x)

Then I need to determine whether these two functions are odd, even, or neither for both problems below:

PROBLEM THREE:

f(x) = x3 + x

PROBLEM FOUR:

h(x) = x2 - x4

Lastly, I need help finding the domain for each function on these two problems:

PROBLEM FIVE:

1 3

_____ + ______ This is 1 over x+7 plus 3 over x-9

x+7 x-9

PROBLEM SIX:

f (x) = ? 3
