1 Express the following rule in function notation: “subtract 6, then divide by 9”. Select the correct answer:

2 True 2.False

3

4 Find a function of the line segment joining the points (5, 19) and (10, 34). Select the correct answer: f (x) = 3x f (x) = 6x f (x) = 3x f (x) = 3x - 8

5 What is the average rate of change of the function f (x) = 4 x - 2 between x = 6 and x = 7? Select the correct answer:

6 True or False: To obtain the graph of g (x) = 27|x + 9|, we must stretch the graph of f (x) = 3|x + 9| vertically by the factor of True 2.False

7 vertex (2.5, ); x-intercepts 0, 5 ; y-intercept 0 2.vertex (3.5, 6.25); x-intercepts 0, 7 ; y- intercept 0 3.vertex (5, 12.5); x-intercepts 0, 4 ; y- intercept 0 4.vertex (- 2.5, ); x-intercepts 0, 7 ; y-intercept 0

8 A rectangular building lot is five times as long as it is wide. Find a function that models its area, A, in terms of its width, w

9 Find f (g (x)) for f (x) = 3 x + 7 and g(x) = 5 x - 9. Select the correct answer: f (g (x)) = 15x f (g (x)) = 15x f (g (x)) = 9x f (g (x)) = 25x - 36
