I need help with this question,
The graph below shows the value of Edna's profits f(t), in dollars, after t months:
graph of quadratic function f of t having x intercepts at 6, 0 and 18, 0, vertex at 12, negative 36, and passes through point 21, 41.25
What is the closest approximate average rate of change for Edna's profits from the 18th month to the 21st month?

ok wait up

ok

rate of change= slope

- anonymous

do you know how to find the slope?

- anonymous

since you are not answering i will show ya

- anonymous

slope=\[\frac{ y2-y1 }{ x2-x1 }\]

- anonymous

so your two points from 18 months to 21 months is: (0,18) and (21,41.25).

- anonymous

Hey sorry it wouldn't let me type lol

- anonymous

plug the points into the slope formula and you get:\[\frac{ 41.25-18 }{ 21-0 } =\frac{ 23.25 }{ 21 }\]

- anonymous

thats the rate o change :3

g'night btw
