Create a unique parabola " pick your own values for a, b and c"
if a is negative the parabola opens down (rainbow) and when a is positive the parabola opens up (smile)
y-intercept "the value of y when x = 0"
determine the zeros " set y = 0 and find the values of x"
do you understand what to do?
I need help with the equation
read my very first response
a, b and c are integers
f(x) = 3x2 + 2x + 4
ok go through every step and let me know if you need more help
when x = 0 what is the value of y?
that equation has no x intercept can you choose one for me ?
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?
do you know the quadratic formula or how to complete the square?
now let me go through it so you see all that I did and put it in the format of my original response
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..
