Select the correct answer. If x is a number that is 7 more than y, how do you express was a function of y?
OA. X= Ry = 7+ x
OB. x= Ry) = 7+ y
Oc. y = f(x) = 7x
OD. y = Rx) = y-7
O E. y=Rx) = 7+ y

Write the inverse of the logarithmic function used to represent the situation in model 1, f(x)=3+2in x . express the answer in radical form.
