4-119.
A parabola has vertex (2, 3) and contains the point (0, 0). 4-119 HW eTool (Desmos). Homework Help ✎
If this parabola is a function, find its equation.
Suppose this parabola is not a function, but is a “sleeping” parabola. Find its equation.
Use the equation y = a(x − h)2 + k; if (h, k) = (2, 3); at (0, 0).
0 = a(0 − 2)2 + 3
−3 = a(4)
Use the equation x = b(y − k)2 + h; if (h, k) = (2, 3); at (0, 0).
Use the eTool below to graph the equations.
