For the graphed exponential equation, calculate the average rate of change from x = 1 to x = 4. Graph of f of x equals 0.8 to the x minus 4 power, minus 6.

−one third.

−five eighths

−four fifths

−seven eighths

Verified Answer :

i just took this test online and i got -1/3.

and -1/3 was the correct answer.

hope this helps in anyway :D

Answer:

average rate of change = \(\frac{-1}{3}\)

Explanation:

I have attached the graph of the given function below.

From the graph, we can note that:

at x = 4 ........> y = -5 ...........> point is (4, -5)

at x = 1 .........> y = -4 ...........> point is (1, -4)

To get the average rate of change, we use the formula:

m = \(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\)

Substitute with the points we got:

average rate of change = \(\frac{-5--4}{4-1} = \frac{-5+4}{3} = \frac{-1}{3}\)

Hope this helps :)
