Question

y=x^2-7x+12
need axis of symmetry, vertex, mx/min value, y-intercept
HELP PLEASEEE AND THANKS!!!

Answer 1

first coordinate of the vertex is always \(-\frac{b}{2a}\) which in your case its
\[-\frac{-7}{2\times 1}=\frac{7}{2}\]

Answer 2

that is also your axis of symmetry,
\[x=\frac{7}{2}\]

Answer 3

okay i just took note of that equation to remember..could you help me out with vertex also? @satellite73
