Question

How do I set up the following problem:
f(x)=x3(to the third power) +1 with the points [2,3] and [-1,1]
very new to calculus and pretty unsure of myself
thank you!!

Answer 1

f(x)=x^2+1

(2,3) (-1,1)

what are you supposed to find?

Answer 2

The problem reads:
Find the average rate of change of the function over the given interval or intervals

problem 1:
f(x) =x^3+1
points:
[2,3] [-1,1]

Answer 3

average rate of change is basically the slope formula

if you drew a line from [2,3] to [-1,1] it would be tangent to some point on f(x)

anyway: slope = (f(2) -f(-1))/(2-(-1))
