8x - 3x - 7 = 23
5x - 7 = 23
5x = 30
x = 30/5 = 6
The domain of a function is the set of values of x in which the function can be calculated.
The range of a function is the associated values of the function respect to the domain.
You have the following function:

In order to determine the domain and range of the previous function, you consider that the given function is available for any value of x. Then, you have:
dom y: -∞ ≤ x ≤ ∞ : (-∞,∞)
The range of the function can be determine by noticing, on the graph, that the maximum value of the function is y=3 and also you can notice that there is no a limit for negatives values of the function. Then, you have:
ran y: -∞ ≤ y ≤ 3 : (-∞,3]
Whats the question that you have and remember theres always google
Answer:
Option D. y=4x+35
Step-by-step explanation:
From the graph take the points (5,50) and (50,250)
<u><em>Find the slope</em></u>
The formula to calculate the slope between two points is equal to

substitute the values


Find the equation of the line in slope intercept form

we have

substitute

solve for b

substitute

therefore
The equation that BEST models the data is
