Answer:
what triangle
Step-by-step explanation:
Average rate of change of the function 
Solution:
Given function:
from x = 1 to x = 5
Substitute x = 1 and x = 5 in f(x).


Let us find the average rate of change of the function.
Average rate of change

Here a = 1 and b = 5.

Substitute f(5) and f(1).



Average rate of change of the function 
its an obtuse angle so each equation should equal 180
Hint: (9y+7) = 180 and (2y+98) = 180
hope this helps pls mark me brainliest
