The domain of a function is the set of all possible inputs for the function.
What are the domain and range?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
Let y = f(x) be a function with an independent variable x and a dependent variable y.
If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that chosen x-value is said to belong to the domain of the function.
The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x).
Hence, the domain of a function is the set of all possible inputs for the function.

Answer:
40 & 56
Step-by-step explanation
Use a multiple table to keep ratio.
Find correct difference by subtracting products.
___[4]__[6]__[8]__
5 [20] [30] [40]
<u>7 [28] [42] [56]</u>
[8] [12] [16]
5 * 8 = 40
7 * 8 = 56
56 - 40 = 16
Answer:
The answer is D. Yes; the graph passes the vertical line test.
Answer: No. It's not proportional
Step-by-step explanation:
The direct proportion in mathematics is expressed as:
y = kx
where
y = $200
k = constant
x = $7.50
We then solve for k
y = kx
200 = 7.50k
k = 200/7.50
k = 26.67
Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.
