The table of values represents a function f(x) how much greater is the Average rate of change over the interval [7,9] than the interval [4,6]?

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

f(x)=4

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
