This is the question and what I have so far is under it.
"Given the length of a femur, f, in centimetres, a person’s height can be determined using the equation H=2.4f+61.4, where H is the height of the person in centimetres. Suppose this equation has a margin of error of ±3.4cm and that a femur is 43.2cm. Write an absolute value inequality that describes this person’s height and solve the inequality to find the range of possible heights."
I get that the person's height is that equation with H and they give the length of the femur but I do not know how to set the equation in terms that it stays within the ±3.4cm range. I also think I may have the wrong idea about what the question is asking.
