There are 3 CRITICAL points of a parabola. They are:
\n" );
document.write( "1) the y-intercept (it's obvious that this is - 5)
\n" );
document.write( "2) the x-intercepts, if any [solving the equation for x, by setting f(x) = 0 will accomplish this task, and also, this equation can be FACTORED]
\n" );
document.write( "3) the VERTEX (this is found by determining the x-coordinate of the vertex, using the formula: \"matrix%281%2C3%2C+x%2C+%22=%22%2C+-+b%2F%282a%29%29\", and then substituting this x-value into f(x)
\n" );
document.write( "   to get the y-coordinate of the vertex. These 2 coordinates will give you the vertex of the parabola, which by the way is a MINIMUM, as indicated by the
\n" );
document.write( "   leading coefficient being > 0. Alternatively, you can convert the function to the vertex form of a parabola, but that may be too much work! \n" );
