The function f is defined by f(x)= 12/x + 1/2 . use this formula to find the following values of the function. f(2x+3)

F(2x+3) = 12/(2x+3) +1/2

Step-by-step explanation:

Put the argument of the function where the variable is. You can simplify if you want, but the original function definition is not simplified, so we assume it is not required.

F(x) = 12/x + 1/2

Put (2x+3) where x is:

F(2x+3) = 12/(2x+3) + 1/2

Comment on the function

If you intend f(x) = 12/(x +1/2), then you would do the same thing: put (2x+3) where x is. In this case, you could combine the +3 and the +1/2, if you want.

... F(2x+3) = 12/((2x+3) +1/2) = 12/(2x +3.5)
