The answer is: " <span>3x² − 17 " .

f(x) = 3x + 1 ;

If g(x) = x² − 6 ;
then: (f o g)(x) = f(x² − 6) = 3x + 1 ;
= 3(x² − 6) + 1 = 3x² − 18 + 1 ;
= 3x² − 17 .

Answer: True
Step-by-step explanation:
This is true because the sample are randomly selected. When we say "random" it means selection is being made fairly without taking into consideration any factors such as age, sex, religion, etc. The selection is not bias in that regard as such the population has the same chance of being selected.
A is the right one:
a. 3:4=9:12
3×3:4×3=9:12
To simplify into 1 fraction, remember, we must make the denominator the same
x/ (x-1 ) - 1/ (2-2x)
= -x/ -(1-x) - 1/(2-2x) [see the similarity now? ] [whatever we multiply for the denominator, as long as we multiply to the numerator, it will be ok]
= -2x / -(2-2x) + 1/-(2-2x)
= (-2x+1 )/ -(2-2x)
=(2x-1)/(2-2x)
