Finding The Vertex? How would I find the Vertex of this equation? 3x^2-12x+16

paintmeblue | Student

that's a quadratic function. the formula for a quad. function is 


 to find the x-value of the vertex, use the equation x= -b/2a  


so a is 3. b is -12. c is 16.

x=-b/2a   -(-12) / 2(3) =  12/6  =  2 

then you plug in that value as x in your equation.


=3(2)^2 -12(2)+16

=3(4) - 24 +16


=4    4 is your y value of the vertex.

the vertex is (2,4)
