__Interactive Tutorial Using Applet__

__TUTORIAL (1) - Domain and Range of Basic Functions__

1 - click on the button above "plot" to start.

2 - Select a function and examine its graph. Write down its equation .(for example f(x) = x^{3}). Do this for all functions in the applet.

3 - Domain : Select a function, examine its graph and its equation. Find the domain of the function being explored. Do this activity for all functions.

4 - Range : Select a function, examine its graph and its equation. Find its range. Do this activity for all functions.

__TUTORIAL (2) - Comparing Basic Functions__

1 - Select function f(x) = x and function i(x) = | x |. Compare the two function and use the definition of the absolute value to explain how to graph i(x) = | x | from the graph of f(x) = x.

2 - Compare the graphs of l(x) = e^{ x} and m(x) = ln (x). Why are the graphs reflection of each other on the line y = x?

3 - Compare the graphs of h(x) = x^{ 3} and k(x) = ^{3}&radic (x). Why are the graphs reflection of each other on the line y = x?

4 - Compare the graphs of f(x) = x, g(x) = x^{ 2}, h(x) = x^{ 3}, j(x) = √(x) and k(x) = ^{3}√(x). Write inequalities involving x, x^{ 2}, x^{ 3}, √(x) and ^{3}√(x) on the intervals 0 < x < 1 and x > 1?

__TUTORIAL (3) - Intervals of Increase and Decrease and any local minimum or maximum of the Basic Functions__

1 - For each function, write the interval(s) where the function increases and the interval(s) where the function decreases and the coordinate of any local minimum or maximum.

__TUTORIAL (4) - Compare the rate of change of the Basic Functions__

1 - Which of the functions g(x) = x^{2} or l(x) = e^{ x} increases faster as x increases?

2 - Which of the functions f(x) = x or m(x) = ln x increases faster as x increases?

__TUTORIAL (5) - Identify Even and Odd Basic Functions__

1 - An even function f has its graph symmetric with respect to the y axis and therefore satisfy the condistion f(-x) = f(x). List all basic functions that are even.

2 - An odd function f has its graph symmetric with respect to the origin of the system of axes and therefore satisfy the condistion f(-x) = - f(x). List all basic functions that are odd.

3 - List all basic functions that are neither even nor odd.
