Question

(a) All the local maximum and minimum values of the function and the value of x at which each occurs

(x, y) =

(b) The intervals on which the function is increasing and on which the function is decreasing. (Enter your answers using interval notation.)

1.) The graph of a function f is given. Use the graph to estimate the following. (Enter your answers using interval notation.)

(a) The domain and range of f.

(b) The intervals on which f is increasing and on which f is decreasing.

local maximum

(x, y) =

local minimum

(x, y) =

(smaller x-value) local minimum

(x, y) =

(larger x-value)

2) a) Local maximum: x=0, y=4; local minimum at x=-3, y=-2and x=2, y=1
function is increasing on (-3,0) U (unioin)(2,infinity)

and decreasing on (-infinity,-3)U(0,2)

1) a) domain [-5,4]; range[-4,2]

increasing: (-3,0)U(1,2)

decreasing: [-5,-3)U(0,1)U(2,4)
