A polynomial expression can only be categorized into a function if and only if a single input can only have one and only output. This means that there should be no more than one dissimilar values of y for the same value of x.
Evaluating the givens above, it can be observed that there are two -1's as an x-coordinate and it has two outputs, 0 and 1. Thus, we can remove either (-1,0) or (-1,1) for the relationship to become a function.

Step-by-step explanation:
Answer:Given a rectangle, the general equation for the perimeter is P=2l+2w and area is A=lw where l is the length and w is the width.
Let x = width and x+10 = length
So the equation to solve becomes 40=2x+2(x+10) so x=5 thus the width is 5m and the length is 15m.
Thus the area is 5⋅15=75m2
Step-by-step explanation:
Subtract 4/7 on both sides to get b=-4/7-3. Then simplify.
