f(x)=\ln x\implies f'(x)=\dfrac1x
g(x)=x^2-1\implies g'(x)=2x

You have 2x^2>1 for all x\ge1, and dividing by x gives 2x>\dfrac1x, or g'(x)>f'(x). By the racetrack principle, then, it follows that g(x)>f(x).

For the graphed function f(x) = -(5)* - 3 + 2, calculate the average rate of change from x = 3 to x = 4.
Ilia_Sergeevich [38]

Answer:

-4

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is \frac{f(b)-f(a)}{b-a}

The given function is f(x)=-5^{x-3}+2.

f(4)=-5^{4-3}+2=-3.

f(4)=-5^{3-3}+2=1.

The average rate of change from x=3 to x=4 is given by:

\frac{f(4)-f(3)}{4-3}

\frac{-3-1}{4-3}=-4
