+654 A linear function is a function that represents a line,
y = 4x + 4
There are more advance functions, like quadratics
y = x^2 +4x + 9
And power functions
y = 3x^8
Polynomial functions
y = 3x^4 + 2x^2 + 8x + 9
Exponential
y=3^x
Rational
y = (4x^2+4x+4)/(9x+9)
Logarithmetic functions
y = 3lnx+b
Sinusodial
y=3sinx+4
Whew!!
Lots of functions
