Answer:
The derivative is

Step-by-step explanation:
The function is given by

Differentiate with respect to x, we get

Answer:
2x+1
Step-by-step explanation:
that's a hard question
we know that g(x)= x-3
so f(g(x))= f(x-3)
we put it in the equation :
f(x-3)= 2(x-3) +7 = 2x-6+7 = 2x +1
I believe it would be 12 because 9 min divided by .75 a rotation gets 12 rotations
100 times as bigger because it is in the 109s
