The general form of each is as follows, Linear: $f(x) = ax+b$ Power: $f(x) = x^n$ Exponential: $f(x) = b^x$ Quadratic function: $f(x) = ax^2+bx+c$ Polynomial of degree 5: $f(x) = ax^5 +bx^4+cx^3+dx^2+ex+f$ Rational function: $f(x) = P(x)/Q(x)$ where both $P(x)$ and $Q(x)$ are polynomials.

Work Step by Step

Examples are: a) $f(x) = 4x+2$ b) $f(x) = x^{5.3}$ c) $f(x) =3^x $ d)$f(x) = 2x^2+2$ e) $f(x) = 27x^5 - 2x+1$ f) $f(x) =\frac{x^2-1}{x+3}$
