Solve the problem.Research has shown that the likelihood of adult alcohol abuse is related to the amount of corporal punishment received as a teenager. This relationship can be described by the model f(n) = 1.3
+ 29where P = f(n) represents the percent chance of adult alcohol abuse for a person that experienced n incidents of corporal punishment as a teenager.i) Is f an increasing function, decreasing function, or neither? What does this mean in terms of alcohol abuse?ii) Use the model to estimate the percent chance of adult alcohol abuse for a person that experienced 4 incidents of corporal punishment as a teenager.iii) Find a formula for f-1.iv) Find f-1(35). What does your
result represent in terms of alcohol abuse? What will be an ideal response?
