What is the answer to this problem and how do you solve the problem? 2x^-2 y^-3/(3a^-4)

Find the value of x for which the lines are parallel.

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

Iknow the answer but the calculator doesn't seem to give the right one
