First of all, x cannot ever equal -1 because if it does then in the original equation you'd be dividing by 0, which is not possible. anything divided by 0 is undefined.
I think the error was in the second step: x(x+1) = 2(x+1) because they didn't need to go from the first step to there. I'm assuming they multiplied both sides of the equation with (x+1) to get rid of the fraction, but since both sides have (x+1) as the denominator the (x+1) would've cancelled out instead of multiplying with the numerator.
Correction:
as u can see, in the second step of this correction, the (x+1)s on both sides cancel out so only the numerators remain.
Hope this helps!
Functions can be modeled by equations, tables and graphs
- The equation that models the function is
- The domain of the function is the set of whole numbers
- The company should expect 4 box office gross in week 10
<h3>How to determine the function</h3>
From the question, we have the following ordered pairs
(x,y) = (0,1) and (4,2)
The function is a linear function.
So, we start by calculating the slope (m) using:
Substitute known values
The equation is then calculated as:
This gives
The domain of the above function is the set of whole numbers
Substitute 10 for x, to calculate the number of box office gross for week 10
Approximate
Hence, the company should expect 4 box office gross in week 10
