Find, in ascending powers of x, the first 3 terms of the expression (1+kx)^4 (1-4x)^3.If the coefficient of x is zero, find the value of k and the coefficient of x^2.

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
