The engineer designing a parabolic arch knows that its equation has the form
y = ax2 + bx + c.
Use the information in the illustration to find a, b, and c. Assume that the distances are given in feet. (Hint: The coordinates of points on the parabola satisfy its equation.)

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x? y? z? , with vertices x? (4, -2), y? (4, -3), and z? (1, -4). the type of transformation that triangle xyz undergoes is a . triangle x? y? z? then undergoes a transformation to form triangle x? y? z? , with vertices x? (4, 2), y? (4, 3), and z? (1, 4). the type of transformation that triangle x? y? z? undergoes is a .
