|
Find out the value of x = -b/2a
and then find the value of y for all the value x .
If the leading coefficient is positive, the parabola opens up
Solve for x = -b/2a
Then calculate the values for y by making a table at x = -1,-2,0 ,1,2,3 .......
If the leading coefficient is positive, the parabola opens up
Firstly, find out all the coordinates of x and f(x) for all equations.
If the leading coefficient is negative, the parabola opens down
First, make the table for finding out all the values of x and f(x)
You can find out the vertex by ,
x = -b /2a
If the leading coefficient is positive, the parabola opens up
Find out the value of x = -b/2a
And then calculate for f(x) by putting x = 0, 1, 2, ....-1,-2...
If the leading coefficient is negative, the parabola opens down
