What is the vertex of the quadratic function f(x) = (x-6) (x+2)
Volgvan
Well, notice, we can pretty much see the x-intercepts if we set f(x) = 0, clearly they're just 6 and -2,

\bf \stackrel{f(x)}{0}=(x-6)(x+2)\implies &#10;\begin{cases}&#10;0=x-6\implies &6=x\\&#10;0=x+2\implies &-2=x&#10;\end{cases}

now, this is a quadratic equation, since it only has 2 solutions at most, recall your fundamental theorem of algebra.

so, the vertex will be right in middle of those two x-intercepts.

what's between -2 and 6?, well is +2 or just 2, so x = 2.

so we know the x-coordinate for the vertex is the halfway point of 2, what's the y-coordinate?

f(x) = y = (2 - 6)(2 + 2)

y = ( - 4)( 4 )

y = -16

thus the vertex is at, well you already know.
