Question

Find the average rate of change of f(x)=3x^2+1 from 4 to 6.

Answer 1

rate of change is also the same as asking for derivative. are you familiar with derivatives or the definition of a derivative?

Answer 2

The average rate of change is just the slope of the secant between the two points on the function.

Answer 3

@abb0t not really

Answer 4

\[\large \frac{ f(b)-f(a) }{ b-a }\]

Answer 5

Or in other words$$\frac{f(6)- f(4)}{6 - 4}$$

Answer 6

@abb0t @Alchemista thanks
