The first answer is c
42cm(2)
Answer: a) 
Step-by-step explanation:
Since we have given that

a.) Find the inverse of f(x) and name it g(x).
Let f(x) = y
So, it becomes
Switching x to y , we get


b) . Use composition to show that f(x) and g(x) are inverses of each other.

Similarly,

so, both are inverses of each other.
c) Draw the graphs of f(x) and g(x) on the same coordinate plane.
As shown below in the graph , Since for inverse function we need an axis of symmetry i.e. y=x
And both f(x) and g(x) are symmetry to y=x.
∴ f(x) and g(x) are inverses of each other.
You would take 1818÷33=55.09
55.09 is how many toothpicks it took for each step made
Then you would take 55.09×55=3029.95
You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up
two units to the left i think
Im in 8th grade :/
If not the answer that I got is 26/57 = [849 x(x= 372.25)]/5
