F°g(x) = (3x-2)² -1
= 3x(3x-2)-2(3x-2) -1
= 9x² -6x-6x+2-1
=9x²-12x+1

36÷4. 4 goes into 36, 9 times. Do your check work, which would be 9x4=36√. Hope that helps!
You are lazy... do it on your own.
Upper Tolerance
Remark
The 11/16 is the only thing that will be affected. The three won't go up or down when we add 1/64 so we should just work with the 11/16. We need only add 11/16 and 1/64 together to see what the upper range is. Later on we can add 3 into the mix.
Solution
<u>Upper Limit</u>

Now change the 11/16 into 64. Multiply numerator and denominator or 11/16 by 4

Which results in

With a final result for the fractions of 45/64
So the upper tolerance = 3 45/64
<u>Lower Tolerance</u>
Just follow the same steps as you did for the upper tolerance except you subtract 1/64 like this.

Your answer should be 3 and 43/64
