If <em>X</em> is uniformly distributed on the interval (0, 12), then its PDF is
or simply
and the zero-elsewhere case is assumed.
Whether you include 0 and 12 in the domain is irrelevant, since the probability that <em>X</em> = 0 or <em>X</em> = 12 are both zero.

So the problem asks for two conditions:
<em>1. Write the quadratic function in factored form. </em>
<em>2. The vertex has an x-coordinate of 3.</em>
Then the equation (1) must be written as follows:

To satisfy the two conditions:
So we are free to choose the value of one root, say:
Thus:
Finally, the answer is:
The graph of this function is shown in the figure below.</span>
