Find the axis of symmetry and vertex.
y=x^2-8x-7
select one:
a. x = 8; (8,-23)
b. y = 2; (2, -17)
c. x = 4; (4, -23)

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

Twelve less than a number is at most 20
