Question

Rate of change of a function

Answer 1

Looking at the graph, f(0) = 150 and f(3) = 0.

So to find the rate of change netween t = 0 and t = 3, find the slope between these two points.

Answer 2

What are the coordinates?

Answer 3

f(0) = 150 means when x = 0, then y = 150.
Same for other point.

Answer 4

You're welcome.

Answer 5

m=0-150/3-0
m=-150/3
m=-50 ?

Answer 6

correct.

Answer 7

Thank you so much.
