Lesson 1.3
function family
a group of functions that share certain characteristics.
function notation
a way to represent equations algebraically that makes it more efficient to recognize the independent and dependent variables.
exponential functions
includes functions of the form f(x) = a*b to the X power. A and B are real numbers,and B is greater than 0 but is not equal to 0.
linear absolute value functions
includes functions of the form f(x) =alx+bl + c, where a,b and c are real numbers.
quadratic functions
includes functions of the form f(x) =ax squared + bx +c, where a,b,c are real numbers, and A is not equal to 0.
linear functions
includes functions of the form f(x)= ax+b, where a and b are real numbers, and a is not equal to 0
Linear piecewise functions
includes functions that have an equation that changes for different parts, or pieces, of the domain.
increasing function
when both the independent and dependent variables of a function increase across the entire domain.
constant function
when the dependent variable of a function
decreasing functions
when the dependent variable of a function decreases as the independent variable increases across the entire domain.
absolute maximum
when there is a point on a graph that has a y-coordinate that is greater than the y-coordinates of every other point on the graph.
