The graph of which function has an axis of symmetry at x = one-quarter? f(x) = 2x2 + x – 1
f(x) = 2x2 – x + 1
f(x) = x2 + 2x – 1
f(x) = x2 – 2x + 1

In the rectangle below ac=30 units what is de

Solve 2x2 + 8 = 0 by graphing the related function. there are two solutions: . there are no real number solutions. there are two solutions: 2 and -2

Which one ? is the answer and how to find this answer
