Find the vertex of F(x) by using the formula for the xcoordinate of the vertex.
F(x)= 4x^2  3x  6
I don't exactly understand this question. could someone clear it up and help me solve it? Thanks!!

Math 
bobpursley,
factor it:
F(x)=4(x^23/4x ) 6
F(x)=4(x^23/4 x + 9/64)  6  4*9/64
= 4(x3/8)^2 ( )
Well,it is obvious that x=3/8 is the x vertix. Putting that x in, then y= 636/64
check my thinking.
