Solve the equation x^2 + 6 x + 3 = 0 two ways. Express your answers both times in simplest radical form. (a) By Completing the Square (b) By the Quadratic Formula

30 inches

Step-by-step explanation:

Given: A sculptor creates an arch in the shape of a parabola. When sketched onto a coordinate grid, the function

represents the height of the arch, in inches, as a function of the distance from the left side of the arch, x.

To find the height of the arch, measured 3 inches from the left side of the arch, we substitute x=3 in the above function:

Hence, the height of the arch, measured 3 inches from the left side of the arch is 30 inches .
