Answer:
No
Step-by-step explanation:
To obtain the inverse function
let y = f(x) and rearrange making x the subject, that is
y = 3x + 1 ( subtract 1 from both sides )
y - 1 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) = 
5.6 the answer is obviously
Answer:
D) c - 2 = 25 + c + 10√c
Step-by-step explanation:
The given equation is 

Taking square on both sides, we get
Here we used ( a+ b)^2 = a^2 + b^2 + 2ab formula.
c - 2 = 5^2 + (√c)^2 + 2(5)√c
c - 2 = 25 + c +10√c
Answer: D) c - 2 = 25 + c + 10√c
Thank you.
