Question

Can someone please help? Pleeeease! :)

Juliana has created the function f(x) = 3x + 2 over 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.

Answer 1

for inverses, always switch the x and the y
then plug in the value, which in this case is 24
then she would subtract 2
then divide both sides by 3
that should help :)
