I don’t know if you can even read this but make your graph points, rather than 1,2,3,4 etc. Make them 1/4,2/4,3/4,4/4, and 1/2,2/2,3/2,4/3, etc.. at least until you can plot your points. Make the numbers into mixed fractions or improper fractions whatever they call it. Make it to where the top is bigger than the bottom by multiplying the whole number by the denominator.

EXPLANATION
The standard form of a quadratic equation is:

To convert this function to standard form, you follow the steps below:
- Factor 'a' from the variable terms
- Add and subtract the square of half the coefficient of x.
- Factor the perfect squares
- Simplify the constant terms to get the vertex form as

For example:
Given the standard form:

Factor 2 from the variable terms

Add and subtract the square of 3.


Factor the perfect square an simplify

This is the vertex form
