If f(X)= 7x +5/3 - x =6x +5/3
y= 6x +5/3
6x= y-5/3
f^-1(y)=x=(y-5/3)/6
So we can write
f(f^-1(y))= f((y-5/3)/6) = 6 (y-5/3)/6 +5/3= y-5/3+5/3= y
The same result can be obtained for f^-1(f(x))=x
If the function is f(x)= 7x +5/(3-x) then it is not invertible since it is not injective (pictures)
Answer:
square root 48
Step-by-step explanation:
It is square root 48 because it is between 7 and 8 not exactly if it was exactly 7 and 8 it would be square root 56
I have no idea like I do not know like I have no clue what is going on
Hello there!
Your answer is none of the above.
The answer for a would be -9, which is rational
The answer or a would 1/3, which is rational
The answer for c would be 3, which is rationonal
The answer for D would be 1/9, which is rational
Hope I helped!
