What is the equation of the circle with center (6,7) and radius 3?
(x - 6)^2 + (y - 7)^2 = 9
(x + 6)^2 + (y + 7)^2 = 9
(x - 6)^2 + (y - 7)^2 = 16
(x + 6)^2 + (y + 7)^2 = 16
3.
Convert to vertex form: y = x^2 + 4x + 3
y = (x+2)^2 - 1
y = (x-2)^2 + 1
y = (x+2)^2 + 1
y = (x-2)^2 - 1
4.
What is the domain of f(x) = 1 / (x^2 - 4)?
All real numbers
All real numbers except 2 and -2
All real numbers except 0
All positive real numbers
5.
What is the equation of the circle with center (3,4) and radius 2?
(x - 3)^2 + (y - 4)^2 = 4
(x + 3)^2 + (y + 4)^2 = 4
(x - 3)^2 + (y - 4)^2 = 16
(x + 3)^2 + (y + 4)^2 = 16
6.
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
