Answer:
Not a function
Step-by-step explanation:
If it was a function there should be only one values for every x, in this case there is two values for x=0. Doesn't pass the vertical test.
Not a solution I believe.
there's not enough information to solve
Perimeter = 2(length + width)
59 = 2(14+x)
59 = 28 + 2x
31 = 2x
15.5 = x
Width = 15.5
