Question 6

See attachment for graph of f.

Let MV = max values

Let mV = min values

MV = f(2.36, 15.55)

mV= f(-0.86, -0.87)

Function Increasing:

(-infinity, -0.84), (0, 0.65), and (0.65, 2.36)

Function Decreasing:

(2.36, -infinity)

You say?

Question 7

See attachment for graph of g.

Intercepts:

(0, -4), (4, 0)

Find g(-5).

g(x) = 2x + 1

g(-5) = 2(-5) + 1

g(-5) = -10 + 1

g(-5) = -9

Find g(2).

g(x) = x - 4

g(2) = 2 - 4

g(2) = -2
