5 f(x) = (x + 1)(x - 5)| a f(n)= |(x + 1)(x - 5)| has three solutions. What is the value of f(n)? How would you describe the location of this solution? b f(m) = (x + 1)(x - 5)| has two solutions. What is the set of values for f(m)? How would you describe the locations of values in this solution set?​
