9. Use vertex form to write the equation of the parabola.

A. y = (x + 3)^2 - 3

B. y = 2(x - 3)^2 - 3

C. y = 2(x - 3)^2 + 3

D. y = 2(x + 3)^2 - 3

Which function has the smallest y-intercept value

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

One side of a rectangle is 7 feet shorter than seven times the other side. find the length of the shorter side if we also know that the perimeter of the rectangle is 306 feet.
