Write the equation of the parabola shown in the graph. (−5,4)(−4,0)(−3,0) 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. (−5,4)(−4,0)(−3,0) Write your answer in the form y=a(x–p)(x–q), where a, p, and q are integers, decimals, or simplified fractions.
Identify p and q: Identify the values of p and q from the given points where the parabola crosses the x-axis. Points (−4,0) and (−3,0) are x-intercepts, so p=−4 and q=−3.
Write parabola equation: Write the equation of the parabola using the form y=a(x−p)(x−q). Substitute −4 for p and −3 for q: y=a(x+4)(x+3).
Find value of a: Use the point (−5,4) to find the value of a. Substitute −5 for x and 4 for y in the equation: 4=a(−5+4)(−5+3).
Solve for a: Simplify and solve for a: 4=a(−1)(−2), 4=2a, a=2.
Final parabola equation: Write the final equation of the parabola substituting a=2, p=−4, and q=−3 into y=a(x−p)(x−q): y=2(x+4)(x+3).
