Curves (Basic math review)

These are the most important curves you should know.

Function	Shape	Graph
y = mx + b	Line
y = x2	Parabola
y = ax3+bx2+cx+d	Cubic equation
x2 + y2 = r2	Circle
x2 + y2 = r2 a2     b2	Ellipse
x2 – y2 = r2 a2     b2	Hyperbola
y = 1/x	Inverse proportion
y = sin x	Sine wave
y = log x	Logarithmic function
y = ex	Exponential function
y = e-x2	Gaussian function, Normal distribution, Bell curve
