In f(x)=(x+3/4), it is supposed to be x+3 over 4, and not 3/4. Anyway, the answer might be D, because that is the answer that comes closest to the actual answer, which is f^-1(x)=-3+4x.
If you need help with any other math problems in the future or anyone who is just googling this question, try this calculator. It'll save you so much time.

Verified answer
y =x + 3/4...solve for x....4y = 4x + 3 ---> x = [ 4y-3 ] / 3...none of those listed
hence I deduce that you made a typing error...y = [ x + 3 ] / 4--->
x = 4y - 3...A)....don't become hooked up with the symbols x & y
the inverse function is [ take a domain element ; multiply by 4 ; then subtract 3 ]
