(-11/8, 0), (3/4,0) is at the same distance from the vertex of their parabola. Determine the equation of axis of symmetry.

Question

anonymous · Answer

The answer is supposed to be -5/16 but I keep getting -5/8. I added -11/8 + 3/4 and divided it by 2.

amistre64 · Answer

add up the points and divide by 2

amistre64 · Answer

the only way they are 2 different points and the same distance away is to have the axis of symm runing between them
