**Identifying Probability Density Functions** In Exercises 25-30, use a graphing utility to graph the function. Then determine whether the function *f* represents a probability density function over the given interval. If *f* is not a probability density function, identify the condition(s) that is (are) not satisfied.

To determine

**To graph:** The function

**Given Information:**

The function

**Graph:**

Now, consider the provided function

Use the ti-83 graphing calculator to construct the graph of the function.

Step 1: Open the ti-83 graphing calculator.

Step 2: Press

Step 3: Press the

And,

Step 4: Press the

The graph of the function

Consider the provided function

A function *f* of a continuous random variable *x* in the interval

And,

The provided function is a constant function and so the function *f* is continuous and nonnegative for all values on the interval

Now, show that
