Composite Functions: Linear to Polynomial
Open a new graphing window. Define linear function f1 in terms of a variable.
Press Enter to graph it.
Now define polynomial function f2 in terms of f1.
Press Enter to graph it.
Notice that the graph of f2 is the graph of a polynomial function.
Define function f3 in terms of f2 so that it results in a shift up by 1.
Define function f4 in terms of f2 so that it results in a horizontal shift.
Change function f1 and see how the corresponding functions change,
while they maintain their relative distance from f1.
