Question

Aidan wrote the interval (-5, 4) and claimed it was equivalent to the graph below. Explain what he did

Answer 1

Answer:

[-5,4)

Step-by-step explanation:

Aidan just made one tiny mistake. They used a parenthese at the front which would mean that the -5 is not included in the interval. But the closed, colored-in dot on the graph means that the -5 IS supposed to be included. So the proper symbol to start the interval would be the square bracket to indicate the -5 is included. So it should be [-5, 4)
