The domain of this function is x = all real numbers.
The range of this function is that y ≥ 0.
To find the domain, you need to look for exclusions. The only numbers that you exclude are when you can't divide by 0 or have a negative square root. Since this problem has no square root symbol or fractions, it is all real numbers.
For the range, we need to find the smallest value of y. y can get no smaller in this problem than when x = 0. In that case y also = 0. Because the lead coefficient is positive (4), we know that the graph is increasing. Therefore, we know that y must always be bigger than 0.
Wee need a photo of the number line to help u sorry
Answer:
Step-by-step explanation:
<u>Given:</u>
- Rate per hour = $6
- Number of hours = 5
- Tips = 15%
Lets the total amount of tabs = t
<u>We have inequality:</u>
- 6*5 + 0.15t ≥ 350
- 30 + 0.15t ≥ 350
- 0.15t ≥ 320
- t ≥ 320/0.15
- t ≥ 2133.33
24x^2+32x is going to be when you distribute the 8x into the parentheses.
