The cost, c(x), for a taxi ride is given by c(x)=2x+4.00, where x is the number of minutes, what does the slope mean for this situation

Identify the function that contains the data in the following table: x     -2         0         2         3         5     f(x)     5         3         1         2         4     possible answers: f(x) = |x| + 1 f(x) = |x - 2| f(x) = |x - 2| - 1 f(x) = |x - 2| + 1
