The table shows values for a function.X 1,2,3,4, Y 4,9,16,25 What equation represents this function?

Question

A.y=x2 B.y=x2+1 C.y=(x-1)2 D. y=(x+1)2

Answer 1

d. You first add 1 to the x value and then square it to get y.

Answer 2

If when you type 'x2' you mean x squared (for clarity should be written as x^2);

The answer is D.

X = 1; (1+1)^2 = 2^2 = 4 = y

X = 2; (2+1)^2 = 3^2 = 9= y

X = 3; (3+1)^2 = 4^2 = 16= y

X = 4; (4+1)^2 = 5^2 = 25= y

Note how y is always the square of the number one greater than the x value.

Answer 3

D

its always d, unless its c
