Draw a parabola opening downward along the arch of the bridge, and plot 5 coordinates on the overlaid graph, stating with the origin (0,0).

Observing the grid overlay on the bridge, here are five points that align with the arch's curve, starting from the origin and moving outward symmetrically:

1. \((0, 0)\) - Origin point
2. \((2, 2)\) - Right side of the arch
3. \((4, -2)\) - Right side, closer to the base
4. \((-2, 2)\) - Left side of the arch
5. \((-4, -2)\) - Left side, closer to the base

These points can be used to fit a parabolic equation in the form \( y = ax^2 + bx + c \). Let me proceed to calculate the values for \( a \), \( b \), and \( c \) that define this parabola.The parabolic equation that best fits the bridge's arch, based on the points chosen, is:

\[
y = -\frac{3}{4}x^2 + \frac{5}{2}x
\]

This equation represents a downward-opening parabola that aligns closely with the arch shape observed in the image.

Would you like a plot of this parabola overlaid on the image, or do you have any questions about the calculation process?

Here are five questions to consider for further exploration:
1. How would the parabola change if we selected different points along the bridge's arch?
2. What role does each coefficient (\(a\), \(b\), and \(c\)) play in shaping the parabola?
3. Could we model the arch with a different type of curve, like a sine function?
4. What would the equation look like if the arch were symmetric around a different point?
5. How would we handle fitting if the arch had an irregular shape?

**Tip:** In parabolic equations, the coefficient of \(x^2\) determines the "width" and direction (upward or downward) of the parabola.

Draw a parabola opening downward along the arch of the bridge, and plot 5 coordinates on the overlaid graph, starting with the origin (0,0).
