PLEASE HELP !!! Which function represents the inverse of function f below? f(x)=3x+5.
A. S(x)= 1/3x+5.
B. R(x)=-3x-5
C. Q(x)=1/3x + 5/3.
D. P(x)=1/3x-5/3

Respuesta :

D is the correct answer. Switch the x for a y and the y for an x. Then solve for y like any other equation. You'll get P(x)=1/3x-5/3.

Hope this helps!

A function assigns the values. The function that represents the inverse of function f(x)=3x+5 is P(x)=(1/3)x-(5/3).

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

If there exist two functions, where one is the inverse of the other, then the composite of this figure will be equal to x. Therefore, if we take P(x) and f(x),

P(f(x)) = (1/3)(3x+5)  - 5/3

         = (3x/3) + (5/3) - (5/3)

         = x

Hence, the function that represents the inverse of function f(x)=3x+5 is P(x)=(1/3)x-(5/3).
