The equation of a parabola that opens up and has the following x intercepts (-3,0) and (4,0) is y=x^{2}-x-12

<h3><u>Solution:</u></h3>

We have to find the equation of a parabola that opens up and has the following x intercepts (-3, 0) and (4, 0)

x-intercepts of the parabola are (−3, 0) and (4, 0)

So, we can form an equation:

Also x = 4

x – 4 = 0

x – 4 = 0 is another factor of quadratic equation.

The quadratic function is:

\begin{array}{l}{y=(x+3)(x-4)} \\\\ {y=x^{2}-4 x+3 x-12} \\\\ {y=x^{2}-x-12}\end{array}

Hence, the equation of the parabola is  y=x^{2}-x-12

How could you use coordinate geometry to prove that segment BC is congruent to segment AD?
liberstina [14]

Answer:

  Prove the lengths are the same

Step-by-step explanation:

When we say segments are congruent, we mean their lengths are the same.

__

Let's see if they are congruent.

  AD = √((3-(-3))² +(2-2)²) = 6

  BC = √((6-0)² +(6-6)²) = 6

AD ≅ BC . . . . their lengths are the same
