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
Answer:
I believe it's A and B
Step-by-step explanation:
It would be D because you have to do the cube root on both sides. What I do is ignore the decimal and add it in later once the math is complete like on this question you can tell by process of elimination that 8 squared is 64 but you’re look for the cube root so that eliminates a and c and now just make sure the decimal is in the right place
