Answer: -3
Step-by-step explanation: plug -2 into f(x)=x^2+10 and you get 14, then plug the -1 into that same equation and end up with 11, now you subtract the 11 from the 14 and get 3 but since you subtracted or in other words the number decreased it would be -3
The rate of change of f(x) over the interval [-2,1] is 3.
What is a Function?
A function is a law that relates a dependent and an independent variable.
The function is f(x) = x² +10
The rate of change of f(x) over the interval [-2,1] is
f(-2) = 4 +10 = 14
f(1) = 1+10 = 11
The rate of change is 14-11 = 3
