Question 1008822: Juliana has created the function f(x) = the quantity of 3x plus 2, divided by 4 to represent the cost of texting on her current plan, where x represents the number of texts. Juliana discovers that, using the inverse function to solve for x = 24, she can predict how many texts she can use for $24. Explain to Juliana how to accomplish this, using complete sentences.

f%28x%29=%283x%2B2%29%2F4 otherwise you must explain or describe the function better. Cost f is a function of x, how many texts. The inverse will be number of texts as a function of cost. Solve for x in terms of f(x). Juliana may wish a different variable name for the cost, once the inverse is found.
