Write the equation of the parabola that passes through the points (−5,−36), (−3,0), (−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 (−5,−36), (−3,0), (−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.
Identify x-intercepts: Identify the x-intercepts from the given points. The x-intercepts are where y=0. Points: (−3,0) and (−2,0) are x-intercepts.
Set p and q: Set p and q as the x-intercepts. p=−3, q=−2. Write the equation in the form y=a(x−p)(x−q). y=a(x+3)(x+2).
Use point to find 'a': Use the point (−5,−36) to find the value of 'a'. Substitute x=−5 and y=−36 into the equation. −36=a(−5+3)(−5+2). −36=a(−2)(−3). −36=6a.
Solve for 'a': Solve for 'a'. −36=6a. Divide both sides by 6. a=−6.
Write final equation: Write the final equation using the values of a, p, and q. y=−6(x+3)(x+2).
