Question

what is the equation of the axis of symmetry for the function shown below y+5=-2(x-2)^2

Answer 1

if you draw the graph, the symmetry is at x=2

Answer 2

x = -b/2a from the general standard form equation y = ax2+bx + c

Answer 3

so convert your equation to standard form and solve using above.

Answer 4

x= h in the general vertex form equation y = (x-h)2 + k

so modify your equation to THAT form and you have h
