Let us assume that the number of alternative schools in the county are x in number.
It is given that the number of charter schools is 4 less than twice the number of alternative schools. So we can write, the number of charter schools is 4 less than twice of x. In equation form this can be written as:
Number of Charter Schools = 2x - 4
It is given that number of charter schools is 48. So we can write:
48 = 2x - 4
2x = 52
x = 26
x was the number of alternative schools. Therefore, there are 26 alternative schools in the county.

Step-by-step explanation:
(a)
The domain of a function denotes the upper and lower limits of the x co-ordinate values, over which the function is defined.
Here, the x co-ordinates over which the function is defined are from -9 to 7.
Hence ,the domain is: -9 ≤ x ≤ 7
(b)
The range of a function denotes the upper and lower limits of the y co-ordinate values, which the function gives.
Here, the y co-ordinates over which the function gives are from -6 to 4.
Hence ,the domain is: -6 ≤ y ≤ 4
