Using the graph below, calculate the average rate of change for f(x) from x = 0 to x = 2.

OpenStudy (anonymous):

x = −4 x = −2 x = 2 x = 4

If this is calculus, take the derivative of the equation first If this is algebra, find the slope at two locations on the curve between given domain of 0 to 2 and average them

OpenStudy (anonymous):

x = 4

OpenStudy (anonymous):

this is algebra, i got -2.

OpenStudy (anonymous):

is that right?

OpenStudy (anonymous):

@Nurali

OpenStudy (anonymous):

It is 4, since to find the average rate of change you divide rise over run. Rise is 8 and run is 2 so you get 8/2 = 4

tyysm:)

OpenStudy (anonymous):

can you help me with one more?

OpenStudy (anonymous):

Sure!

OpenStudy (anonymous):

Which graph models the function f(x) = −2(3)x?

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

@navk ?

OpenStudy (anonymous):

f(x) = −2(3)x is it just f(x) = -6x ?

OpenStudy (anonymous):

The function is not clear please type it again

OpenStudy (anonymous):

Which graph models the function f(x) = −2(3)^3

OpenStudy (anonymous):

that's the question.

OpenStudy (anonymous):

Its x=4
