I am needing help with how to solve 4, 5, and 6.

4. (6 pts.) Use an algebraic test to determine whether the given function is even, odd, or neither. (a) f (x) = =. In (x2) (b) g(x) = x+5 x - 4 5. (3 pts.) The function P(t) gives the population of a town t years after 2015. If the average rate of change of P(t) on the interval 0 S t 10 is -20 people/year, what is the average rate of change of Q(t) = 2 : P(t) + 1 on the interval 0 S t - 10? 6. (4 pts.) The graphs of two related functions are given below. Determine the relationship between the two functions, and then write a formula that relates the graph of g to the graph of f. (You do not need to find formulas for each individual function.) Graph of f Graph of g HNWD -7-6-5-4-3-2-1 0 1 2 3 4 5 U B WN H g (x) =
