Answer:12916.66
Explanation:
f(5) = 2/3(5)^5
f(5) = 2/3 (3125)
f(5) = 2083.33
f(10) = 2/3(10)^5
f(10) = 2/3 (100000)
f(10) = 66666.66
You want to subtract the results from eachother
66666.66 - 2083.33 = 64583.33
Now you want to divide this number by how much f(x) did
it went up by 5 so we divide by 5
64683.33 / 5 = 12916.66
