What is the average rate of change from x=-4 to x=1

- 1

Step-by-step explanation:

The average rate of change of f(x) in the close interval [ a, b ] is

here [ a, b ] = [ - 4, 1 ]

From the graph

f(b) = f(1) = - 1

f(a) = f(- 4) = 4

average rate of change = = = - 1

180

step-by-step explanation:

costs the what? what is the cost of the pants?
