Question

A certain statue at a monument has a perimeter of rope hung by poles. Between each pole the rope forms a U-shape that, like a parabola, can be expressed by the equation y=(x−3/2)2+5/4
. Suppose you were to graph the equation; at what point would the graph cross the y-axis?(1 point)
y=

Answer 1

Set x = 0. y = (0 − 3/2)^2 + 5/4 = 9/4 + 5/4 = 14/4 = 7/2.
So the graph crosses the y-axis at (0, 7/2), y = 7/2.
