Determine whether the curve is a function

14 is a function, 15 is also a function

Step-by-step explanation:

You can use the vertical line test to see if a curve is a function. If the vertical line intersects the graph more tha one time, it not a fuction. If only one time, it is a function.

14. Yes

15. No

Step-by-step explanation:

14. Passes vertical line test.

15. Does not pass vertical line test.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
