The distance around a circular wading pool is 39.25 m. How far does a lifeguard have to walk from the edge of the pool to get to the centre of the pool? Pls answer quickly. Thx

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
