You can put this solution on YOUR website! Let f(x) = | 3 – 7x |. Find all x for which f(x) > 10
We have |3-7x| > 10 when either 1.) 3-7x > 10 or when 2.) -(3-7x) > 10.
1.) 3-7x > 10
7x < 3-10
7x < -7
x < -1
2.) -(3-7x) > 10
7x-3 > 10
7x > 10+3
7x > 13
x > 13/7
The solution set for f(x) is all real numbers x where x < -1 or x > 13/7.
