Linear and Exponential Functions

Linear Functions
On a Graph: straight line
In a Table: ADD or SUBTRACT the same amount to the y-values
In an Equation: y=mx+b
3
Exponential Functions
On a Graph: curved line (not a u)
In a Table: MULTIPLY or DIVIDE the same number to the y-values
In an Equation: y=a(b)x

Linear Functions (y=mx+b)
m: slope (rise/run or change in y/change in x)
b: y-intercept (where the lines crosses the y-axis or the y-value when x=0)

Multiple Choice
What is the equation for the linear table?
y = 7x + 3
y = 3(7)x
y = 7(3)x - 1
Not a function

Exponential Functions (y=a(b)x)
a: y-intercept (where the curve crosses the y-axis or the y-value when x=0)
b: growth or decay factor (what is being multiplied or divided when you look at the y-values)
Growth if b>1
Decay if b is between 0 and 1
