Question

The least value of the function x^2 + px + q is 3 and this occurs when x = – 2. find the values of p and q

Answers

  1. Answer:
    Hello,
    p=4
    q=7
    Step-by-step explanation:
    The vertex of the parabola is (-2,3)
    Equation of the parabola is  k(x+2)²+3=x²+px+q
    Let’s identify the coefficients:
    kx²+4kx+4k+3=x²+px+q
    so
    k=1
    4*1=p
    4*1+3=q
