Function notes

A function is a rule that relates how one quantity depends on other quantitites

V=IR where

V=Voltage (V)

I=current (A)

R= resistance

s=speed (m/s)

t=time take (s)

If d increases the speed goes up


S=1mi/t t is independent

y=x^2 + 3 time is on the x- axis and independent variable

independent varible represents all possible values of domain

function f of x...f(x)
