Answer:
Step-by-step explanation:
Domain is all possible x- values- since the dots are solid, you include them in the domain-
the lowest X possible is at -11 and the highest is +11
it s a continuous graph, so it will include any and all number between the two ends
By taking the product of the two fractions we will see that the number that goes in the green box is a 6.
<h3>How to add two fractions?</h3>
We only can add two fractions if we have the same denominator in both of them, here we want to transform -2/3 in an equivalent fraction, such that the denominator is 9, so we multiply both the numerator and denominator by 3.
So we need to solve:
From that, we can conclude that the number that goes in the green box is 6.
