1.
Which function represents exponential growth?
f(x) = 2x
f(x) = x^2
f(x) = 2^x
f(x) = log(x)
2.
Simplify: (x^2 + 2x + 1) / (x + 1)
x
x + 1
x - 1
x + 2
3.
Simplify the expression: 2x + 5 + 3x - 2
5x + 3
5x - 3
5x + 1
5x - 1
4.
Simplify: (3x^2y)(2xy^3)
5x^3y^4
6x^3y^4
5x^2y^3
6x^2y^3
5.
Factor completely: x^3 - 8
(x-2)(x^2+2x+4)
(x+2)(x^2-2x+4)
(x+2)(x^2+2x+4)
(x-2)(x^2-2x+4)
6.
Solve: |2x - 6| = 10
x = -2 or x = 8
x = 2 or x = 8
x = -2 or x = 4
x = 2 or x = 4

What is the equation of the parabola with vertex (2,3) and focus (2,5)?
y = (x - 2)^2 + 3
y = (x + 2)^2 + 3
y = (x - 2)^2 - 3
y = (x + 2)^2 - 3
