If f(x)=x^3-x, what is the average rate of change of f(x) over the interval [1,5]?
RSB [31]

Answer:

30

Step-by-step explanation:

Average rate of change=Δf(x)/Δx = [f(x2)-f(x1]/[x2-x1]

Δf(x)/Δx = [f(5)-f(1]/[5-1]

f(5)=5³-5=120

f(1)=1³-1=0

Δf(x)/Δx = [120-0]/[5-1]=120/4=30

Gekata [30.6K]

Answer:

52.5

Step-by-step explanation:

WX curve is 105 degrees

so to find WYX, you need to divide the WX curve by 2:

Select the correct answer.
Leviafan [203]

Answer:

The graph of function g is the graph of function f shifted 6 units up.

Step-by-step explanation:

Given

f(x) = 2^x

g(x) =2^x + 6

Required

Compare g(x) to f(x)

Substitute f(x) = 2^x in g(x) =2^x + 6

g(x) = f(x) + 6

<em>This implies that f(x) is shifted 6 units upward to give g(x)</em>
