Step-by-step explanation:
Alrighty
remember

and
![x^\frac{m}{n}=\sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%5Cfrac%7Bm%7D%7Bn%7D%3D%5Csqrt%5Bn%5D%7Bx%5Em%7D)
and
![(x^m)^n=x^{mn} and [tex]x^0=1](https://tex.z-dn.net/?f=%28x%5Em%29%5En%3Dx%5E%7Bmn%7D%20and%20%5Btex%5Dx%5E0%3D1)
for all real numbers x
and

b.

=

c.
x^0=1
so
that (x^-3y)^0=1
because exponents first in pemdas
so we are left with
x^2y^-1
Rearrange so x is the subject:-
(im assuning the f unction f(x) = (x + 2) / 7):-
f(x) = (x + 2)/7
7f(x) = x + 2
x = 7f(x) - 2
replace f(x) by x and x by another function
f = 7x - 2
Its D
