Which of the sets of ordered pairs represents a function?

1 answer:

3 0

A function WILL NOT have any repeating x values. They can have repeating y values, just not the x ones. So just look at the x values.

so look at x values in A.....are there any repeating x values ? Yes there is....there are repeating 2's...therefore, A is not a function.

now look at the x values in B...are there any repeating x values ? yes there is....there are repeating 9's....so B is not a function.

so neither A or B are functions

To find the radius of the circular storage shed, you will use the formula for finding the volume of a cone (V=1/3 x pi x r^2 x h, where r is the radius and h is the height.

You will substitute in the information you know and then solve for the radius(r).

Please see the attached picture for the steps necessary to get an approximate radius of 2.02 ft as the radius.
