How do you know if something is a function just by looking at the graph?
Passes the vertical line test
Solve for x:
x2-10x+24=0
x=4, 6
Solve for x:
4x - 12 = 0
x = log4(12)

[2, inf)
Multiply:
(x - 5)(x2 + 5x + 25)
x3 - 125
Completely condense:

Solve for x:
ln(x - 1) = 4
x = e4 + 1
What is the range of f(x) = x3 - 2
(-inf, inf)
What is the end behavior of f(x) = 3x2 + 5x3 - 4x4?
As x -> -inf, f(x) -> -inf
As x -> inf, f(x) - > -inf
Simplify:
log3(1/37)
-7
Solve for x:
tan(x) = undefined
x = pi/2 + pi(n)
OR
