Trapezoid WXYZ is shown on the coordinate grid. Trapezoid WXYZ is dilated with the origin as the center of dilation using the ru
le (x, y)→(4x, 4y) to create trapezoid W'X'Y'Z'.
Which statement is true?
Trapezoid W'X'Y'Z' is smaller than trapezoid WXYZ because the scale factor is less than 1.
Trapezoid W'X'Y'Z' is smaller than trapezoid WXYZ because the scale factor is greater than 1.

Answer:
A
Step-by-step explanation:
According to the Factor Theorem, if (<em>x</em> - <em>k</em>) is a factor of a polynomial P(x), then P(k) must equal zero.
We are given that a polynomial function has the zeros 2, √3, and -√3. So, we can let <em>k</em> = 2, √3, -√3.
So, according to the Factor Theorem, P(2), P(√3) and P(-√3) must equal 0.
Testing each choice, we can see that only A is true:
Testing all three values yields that:
Hence, our answer is A.
