1.01 LINEAR FUNCTIONS

Y-Intercepts

Using a Graph

Using an Equation

The y-intercept is found where the linear function crosses over the y-axis. This is also where the value of x is 0.

X-Intercepts

The x-intercept is found where the linear function crosses over the x-axis. This is also where the value of y is 0.

Domain & Range

What is the Domain of the function?

Domain = x-values, input

What is the Range of the function?

Range = y-values, output

( ) = number is not included

​

[ ] = number is included

Real-World Connections

What is the Rate of Change and what does it mean in the context of this problem?

What is the Initial Value and what does it mean in the context of this problem?

Rate of Change = Slope

Initial Value = Y-Intercept

Real-World Connections – Part A

How many cars will the salesperson have sold after 7 months?

Real-World Connections – Part B

If the salesperson leaves the dealership after 10 months, how does it change the domain and range?
