Identify the function that contains the data in the following table:Х-20o235f(x)531224O f(x) = x/ + 1O f(x) = x - 21O f(x) = lx
- 21 - 1Of(x) = lx - 21+1
1 answer:
To identify the function that contains the data in the table, we should first visualize the data.
A graph of the data is shown below:
From the plot above, we can identify that:
The graph above is a graph of f(x) = |x|, translated to the right 2 units and translated upwards 1 unit.
Hence, the function is:

So we have the following system of equations:
We need to solve it by substitution. This means that we have to take the expression for x given by the second equation and replace x with it in the first equation:
So y=-1. If we use this value in the second equation:
So we have x=2 and y=-1 which means that there's one solution. Then the correct answer is A and the solution is (2,-1).
