Question 587434
Please help me solve this quadratic equation y=x^2-25 to find the line of symmetry. I tried using the formula -b/2a, but I got a strange answer, 25/2.
:
In this equation b=0, therefore the axis of symmetry is 0 as you can see if you graph this
{{{ graph( 300, 200, -8, 8, -30, 10, x^2-25) }}}
