(x+3)(x+3)
(x-3)(x-3)
2.
What is the equation of the line that passes through the point (2,3) and has a slope of 2?
y = 2x - 1
y = 2x + 1
y = x - 1
y = x + 1
3.
What is the equation of the parabola with vertex (4,5) and focus (4,7)?
y = (x - 4)^2 + 5
y = (x + 4)^2 + 5
y = (x - 4)^2 - 5
y = (x + 4)^2 - 5

The value of (4^2 - 1) / (4 - 1) is:
3
4
5
6
5.
What is the value of x in the equation: x^2 + 4x - 5 = 0
x = -5
x = -1
x = 1
x = 5
6.
What is the inverse of f(x) = 2x - 5?
f^(-1)(x) = (x+5)/2
f^(-1)(x) = (x-5)/2
f^(-1)(x) = 2x + 5
f^(-1)(x) = (5-x)/2
7.
Solve: |3x - 6| = 12
x = -2 or x = 6
x = 2 or x = 6
x = -2 or x = 4
x = 2 or x = 4
8.
What is the equation of the circle with center (3,4) and radius 5
(x - 3)^2 + (y - 4)^2 = 25
(x - 3)^2 + (y - 4)^2 = 9
(x - 3)^2 + (y - 4)^2 = 16
(x - 3)^2 + (y - 4)^2 = 36

What is the equation of the circle with center (4,5) and radius 3?
(x - 4)^2 + (y - 5)^2 = 9
(x + 4)^2 + (y + 5)^2 = 9
(x - 4)^2 + (y - 5)^2 = 16
(x + 4)^2 + (y + 5)^2 = 16
