The standard form of the parabola is
Step-by-step explanation:
The standard form of a parabola is
.
In order to convert into the standard form, we first separate the variables:
we now divided both sides by 2 to remove the coefficient from and get:
.
We complete the square on the left side by adding 3 to both sides:
now we bring the right side into the form by first multiplying the equation by :
and then we multiplying both sides by to get
.
Here we see that
Thus, finally we have the equation of the parabola in the standard form:
So to label the axes the number of people would be on the left and number of forks on the bottom. choosing your scale means how you would choose to count. the independent variable is the forks and dependent is the people. For the scale I would count by 2s for the x-axis and 1s for the y-axis.
