Write the equation of the parabola that passes through the points (2,24), (4,0), and (−2,0). Write your answer in the form y=a(x−p)(x−q), where a, p, and q are integers, decimals, or simplified fractions.
Q. Write the equation of the parabola that passes through the points (2,24), (4,0), and (−2,0). Write your answer in the form y=a(x−p)(x−q), where a, p, and q are integers, decimals, or simplified fractions.
Find p and q: We have the points (2,24), (4,0), and (−2,0). The points (4,0) and (−2,0) are the x-intercepts of the parabola, so they give us the values of p and q directly.q0 and q1.
Write parabola equation: Now we can write the equation of the parabola in the form y=a(x−p)(x−q) using the values of p and q we found.Substitute 4 for p and −2 for q into the equation y=a(x−p)(x−q).y=a(x−4)(x−(−2))y=a(x−4)(x+2)
Find value of a: Next, we need to find the value of a. We can use the point (2,24) to do this, as this point lies on the parabola.Substitute 2 for x and 24 for y into the equation y=a(x−4)(x+2).24=a(2−4)(2+2)
Solve for a: Now we solve the equation to find the value of a.24=a(−2)(4)24=−8aa=−824a=−3
Final equation of parabola: We have found that a=−3. Now we can write the final equation of the parabola using the values of a, p, and q. Substitute −3 for a, 4 for p, and −2 for q into the equation a0. a1
