Jamal simplified the expression StartRoot 75 x Superscript 5 Baseline y Superscript 8 Baseline EndRoot where x greater-than-or-equal-to 0 and y greater-than-or-equal-to 0. StartRoot 75 x Superscript 5 Baseline y Superscript 8 Baseline EndRoot = StartRoot 25 times 3 times x Superscript 4 Baseline times x times y Superscript 8 Baseline EndRoot = 5 x squared y squared StartRoot 3 x EndRoot

Which describes the error Jamal made?
He should have written the square root of y Superscript 8 in the answer as y Superscript 4, not y squared.
He should have written the square root of x Superscript 4 in the answer as x, not x squared.
He should have written the 5 inside of the radical in the answer.
He should have written the 3 outside of the radical in the answer.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

hope this !
