    if a is negative the parabola opens down (rainbow) and when a is positive the parabola opens up (smile)

    the equation is unique it is your equation the equation will have intercepts I can help you to determine it is not something I can make up once we have a, b and c

    I can do my own then you follow the same steps with this one or you can ask for more help with this which do you prefer?

    a, b, c a = 1 b = -6 c = 5 direction opens up because a is positive determine the y-intercept find f(x) when x = 0 when x = 0 y = 5 determine the zeros set f(x) = 0 and solve for x I used factoring (1,0) and (5, 0) do you see all this in the sketch? the question did not ask but the vertex is at (3, -4) the minimum point and the axis of symmetry is at x = 3. the axis of symmetry is the line that cuts the parabola in half through the vertex take a minute to review do you have any questions?

    I will try and remember not to answer any more of your questions since you don't really appreciate my help..
