Write the equation of the parabola shown in the graph. (−3,0)(−2,−6)(1,0) 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 shown in the graph. (−3,0)(−2,−6)(1,0) 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 (−3,0) and (1,0). These points indicate where the parabola crosses the x-axis, so p=−3 and q=1.
Write parabola equation: Write the equation of the parabola using the form y=a(x−p)(x−q). Substituting p=−3 and q=1, we get y=a(x+3)(x−1).
Find value of a: Use the point (−2,−6) to find the value of a. Substitute x=−2 and y=−6 into the equation y=a(x+3)(x−1).
Calculate a: Calculate a using the substituted values: −6=a(−2+3)(−2−1), −6=a(1)(−3), −6=−3a, a=2.
