Question 276518: One of the accepted functions used to express this correspondence is: h(x) = 1.95 x + 72.85.
where (the domain) x= length of the femur bone in cm and (the range ) h is the height of the female subject in cm. (Brand, 2009).
Show all detail calculations and find answers to 2 decimal precision.
a) Find the height of a female whose femur is 35 cm long


b) Find the length of a femur in a female who is 165 cm tall.


c) What is an invalid value for the domain in this function. Using the function, show why it is invalid using lucid and correct algebraic detail calculations.
