Question

The task is to match the lettered items with the correct numbered items. Appearing below is a list of lettered items. Following that is a list of numbered items. Each numbered item is followed by a drop-down. Select the letter in the drop down that best matches the numbered item with the lettered alternatives.
a.
Not a function

b.
Linear

c.
Non-Linear

1.
y=45-2x

2.
y=45-x2

3.
y2= -x +2

Answer 1

Here is the matching of the lettered items with the numbered items:

1. y = 45 - 2x
   Match: b. Linear

2. y = 45 - x²
   Match: c. Non-Linear

3. y² = -x + 2
   Match: a. Not a function (since y² implies that y can take on both positive and negative values, it does not represent a function in the typical sense).

So the final matches are: 1 - b
2 - c
3 - a
