Applying the Subtraction property of Equality:
The Zero Product property states that:
If then
Then, you know that:
Therefore the most likely factors of the function graphed above are:
Lets call the number 'n'
plus means addition
is means the equal sign
so that as an expression would be
n+4=7
plus means addition
