Question

Average rate of change of f over the interval (30,60). a=15

Answer 1

Here is the graph.

Answer 2

Okay, so the average rate of change formula is \[\frac{ f(b)-f(a) }{ b-a }\]

Answer 3

That graph, makes no sense o-o

Answer 4

That's what I thought! I'm not sure how to figure out the rate of change without a line going through that point?

Answer 5

EXACTLY. I Dunno. because you have to find the Y values, and yano. o-o. Theres no numbers xD
