use the graph to find the local minimum and the local
maximum for the given function.
over the interval (-3, 0], the local minimum is
over the interval [0, 3], the local maximum is
over the interval [0, 57, the local minimum is

(-1.5,-16)

(1,4)

(2.5,-3)

Step-by-step explanation:

Over the interval (-3,0], the local minimum is (-1.5,-16).

Over the interval [0,3], the local maximum is (1,4).

Over the interval [0,57 , the local minimum is (2.5,-3).

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
