Answer:
The Value of X is 5 units
Step-by-step explanation:
We can use the formula for a parabola:

where

is the origin of the parabola and

is some constant scaling factor.
We are given that the center of the arch on the bridge is

. This is our origin. So our equation is:

Now we just need to find c. We can do this by plugging in one of the other points given:


So our final equation for the arch of the bridge is:
the answer is B your welcome
No, not at all.
The general quadratic equation is
Ax² + Bx + C = 0 .
The roots are real only if (B² - 4AC) is not negative.
That means if you graph it, it touches or crosses the x-axis.
If the graph is up in the air and never touches the x-axis,
then it has no real roots.
