Answer:
the average rate of change is 4.
Step-by-step explanation:
Find the average rate of change of f(x)=x^2 on the interval [1,3].
The average rate of change of f(x) on the interval [a,b] is f(b)−f(a)/b−a.
We have that a=1, b=3, f(x)=x^2.
Thus, f(b)−f(a)/b−a=((3))^2−(((1))^2)/3−(1) = 4.

Answer:
13/16
Step-by-step explanation:
(1/8) + (5/16) + (3/8) =
The denominator 8 goes into 16 twice so multiply the top and bottom numbers by 2
(1 x 2) + (5/16) + (3 x 2)
(8 x 2) (8 x 2)
2/16 + 5/16 + 6/16 = 13/16
I hope this helps!
