P.O.D. #34 Feb 18
Find each function value.
1. f(2) if f(x) = x f(9) if f(x) = x – 8
3. f(3) if f(x) = 2x f(6) if f(x) = 2x – 5
5. f(–7) if f(x) = 3x f(8) if f(x) = 3x – 10
Choose four values for x to make a function table for each function. Then state the domain and range of the function.
7. f(x) = x + 7 x
x +7
f(x)

3. M6L1 Outcome:
Students construct linear functions based on verbal descriptions of bivariate data.

4. M6L1 Notes
A linear function can be used to model a linear relationship between two types of quantities.
The graph of a linear function is a straight line.
A linear function can be constructed using a rate of change and initial value.

5. M6L1 Notes
It is an equation of a line in which the rate of change is the slope of the line describes how one quantity changes with respect to another quantity.
The initial value is the y-intercept.
