eMath Instruction - Algebra - Unit 3 - Functions

function : a clearly defined rule that converts an input into exactly one output; x-values cannot repeat

f(x) is equal to : y

y-axis : the line x = 0; the vertical axis

zeroes of the function : the x-value(s) where the function crosses the x-axis; AKA roots = solutions = x-intercepts

a function is said to be positive when... : it is above the x-axis

relative minimum/maximum : one of the highest or lowest points of a function
