A definitely has to be one because it's a fact and you need to know what it looks like. B isn't true because the greatest integer function rounds down values. C is also not correct because a one-to-one graph has one x-value for every y-value. This one doesn't. D has to be true because f[0] = 0 because the Greatest Integer Function requires it to be. And E is also correct because that's in the definition of a Greatest Integer Function. So, your answers are A, D and E.
Answer:
53 bagels
Step-by-step explanation:
The number of bagels, y sold is a function of the square of the time (x) plus 4.

Answer: x<4
Given the inequality:

We want to solve the inequality for x.
First, distribute the bracket on the right side of the inequality.

Next, subtract 10x from both sides of the inequality.

Add 24 to both sides of the inequality.

Divide both sides of the inequality by 6.

The solution to the inequality is x<4.
Answer:
