Quadratic function for vertex coordinates formula for vertex coordinates, no C how to do? y=x2+8x This form is not given to C What about 4ac and C?
What about 4ac and C
Obviously, C = 0, so 4ac = 0
Vertex expression of quadratic function
I don't know if the m in brackets is + or-
What I want is expression. Why do you give me vertex formula
Oh, I'm sorry. I read it wrong
y=[x-(b/-2a)]+(4ac-b^2)/4a
If it's still wrong, I'm sorry. I don't know
