Answer 2

Answer:

quadratic: y = x^2 + 4x + 4

Step-by-step explanation:

Notice that each y value is the square of an integer.

4 = 2^2

9 = 3^2

16 = 4^2

etc.

This is a quadratic equation.

The first ordered pair is (0, 4). 4 is 2^2, so add 2 to x and rthen square the quantity. (0 + 2)^2 = 2^2 = 4. This also works for the other values of x.

The equation is

y = (x + 2)^2

y = x^2 + 4x + 4

Answer: quadratic: y = x^2 + 4x + 4
