Answers:

1) 3/4

2) 2a

3) 2a^2

4) a^5

5) 1

6) x = 8

7) When n = 0 then f(n) = 1

When n = 1 then f(n) = z

When n = 2 then f(n) = z^2

When n = 3 then f(n) = z^3

8) f(5) = 3 + 4 (5 - 1)
f(5) = 3 + 4 (4)
f(5) = 3 + 16
f(5) = 19

f(0) = 3 + 4 (0 - 1)
f(0) = 3 + 4 (-1)
f(0) = 3 + (-4)
f(0) = 3 - 4
f(0) = -1

9) 125

10) 1875

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2
