Answer:
Domain: [0, 4]
Range: [0, 4]
Function? Yes
General Formulas and Concepts:
<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Range is the set of y-values that are outputted by function f(x)<u>
</u>
- Vertical Line Test - no function can have the same x-value for different y-coordinates
Step-by-step explanation:
According to the graph, our x-values span from 0 to 4. Since both are closed dot, they are inclusive in the domain:
Interval Notation - [0, 4]
Inequality Notation - 0 ≤ x ≤ 4
According to the graph, our y-values span from 0 to 4. Since both are closed dot, they are inclusive in the range:
Interval Notation - [0, 4]
Inequality Notation - 0 ≤ x ≤ 4
Since we see that each x-value has a unique y-value and passes the vertical line test.
∴ the relation is a function.

Step-by-step explanation:
2 because 6 multipled by 1/3 is 2 and 2 multipled 3 is 6
Answer:
Checking each term: 5xy2 has a degree of 3 (x has an exponent of 1, y has 2, and 1+2=3) 3x has a degree of 1 (x has an exponent of 1) 5y3 has a degree of 3 (y has an exponent of 3)
Answer:
Let s represent the number of student tickets sold.
Let g represent the number of general admission tickets sold.
s + g = 350
3s + 5g = 1450
