algabra II

linear

Y=x. A straight diagonal line that increases from left to right.

Absolute value

Y=|x|. V-shape decreasing then increasing

Quadratic

X to the 2nd power. U-shaped decreasing fast to slow turn increasing slow-fast

sqaure root

y=(√)x; Starts at (0,0) and curves upward and to the right

cubic

y= x³; Starts as an S-shaped curve that increases from left to right

Cube root

y=∛x a sideways S-shaped curve that increases from left to right.

Rational

Y=1/x; has two seperate curved branches and never touches the x- or y- axis

exponential

y=2x; increases slowly at first and the very quickly.

Logarithmic

Y=log2(x); Increases quickly at first and then more slowly
