Find the average rate of change of f(x)=5x2 - 3 from 3 to 9. The average rate of change of f(x) = 5x2 - 3 from 3 to 9 is
(Simplify your answer.) help

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
