Add it and subtract it by a certain number
Answer:
31500
Step-by-step explanation:
We'll assume that each week, the radio gets new audience who have not yet bought a ticket. Therefore, the sales would be constant for each week. That is to say, 2100 sales weekly since the number of times it's ran is 8 as previously. The sales will therefore be 15*2100=31500 ticket sales
The correct statements regarding the exponential function
- The function is positive on its entire domain.
- The domain is x ≥ 0 to represent the number of years after the bedroom furniture was purchased.
- The y-intercept (0, 1000) represents the initial cost of the bedroom furniture.
<h3>What is an exponential function?</h3>
An exponential function is modeled by:
In which:
For this problem, we have that when x = 0, y = 1000, hence the y-intercept is of (0,a) = (0,1000), and:
When x = 2, y = 722.5, hence we use it to find b, as follows:
1000b² = 722.5
b² = 0.7225
b = sqrt(0.7225)
b = 0.85.
Hence the equation is:
The <u>asymptote is at y = 0</u>, hence the function is positive in the entire domain, and the and the domain is x ≥ 0 to represent the number of years after the bedroom furniture was purchased, as in these problems time is non-negative.

The general equation of a line in slope-intercept form is:
y = mx + b
where m is the slope and b is the constant term.
If x is put equal to zero the equation becomes:
y = b
therefore the constant term b is the intercept on the y axis, or the y-intercept.
