Question 549417: For the following equation, give the x-intercepts and the coordinates of the vertex.
y=x^2-6x-1
The chart needs to be filled out like this:
x-intercept (x,y)= (_____, _____) (smaller x-value)
x-intercept (x,y)= (_____, _____) (larger x-value)
vertex (x,y)= (_____, _____)
I cannot figure out how to fill out this chart please help me

You can put this solution on YOUR website!
the x-intercepts are the roots of the equation (when y=0)
___ use the quadratic formula to find them

the vertex is on the axis of symmetry
___ the equation is ___ x = -b / (2a)
___ solve for x, then plug the value into the equation to find y
