Question

For the following function, find the vertex, the axis of symmetry, and the x- and y-intercepts of the graph.
f(x)=x^2-10x

Answer 1

vertex is
\[-\frac{b}{2a}=\frac{10}{2}=5\] for the first coordinate
second coordinate is -25 , what you get when you replace x by -5

Answer 2

hold on, I'm confused. I thought I needed an ordered pair for the vertex..

Answer 3

and i made a mistake. axis of symmetry is x - 5
vertex is (5,-25)

Answer 4

x = 5

Answer 5

Ohhhhh.... duh, I'm low on sleep. sry
