3. parent function: f(x) = x
Interpreting Graphs
Linear graphs:
parent function: f(x) = x
Y intercept at origin (0,0)
Positive slope rises from left to right
Constant rate of change (slope) of 1
Closer to vertical slope increases(ie greater than 1)
Closer to horizontal approaches 0 (ie less than 1, and greater than 0)
Negative slope falls from left to right

4. parent function: f(x) = x
Interpreting Graphs
Linear graphs:
parent function: f(x) = x
Y intercept at origin (0,0)
Add positive constant represents a shift up on the y-axis
Add a negative constant (subtraction) represents a shift down on the y-axis
Constant term is always the y-intercept (where lines crosses the y-axis)
