Answer:
-8
Step-by-step explanation:
what do you think, when you look at the examples given in the problem definition ?
don't you see the pattern, that f(x) = x+2 ?
f(1) = 1+2 = 3
f(2) = 2+2 = 4
f(3) = 3+2 = 5
so, if we follow this assumption, then
f(-10) = -10 + 2 = -8
Answer:
Option B:
Step-by-step explanation:
To obtain the inverse of the function
, you need to solve the equation for the variable "x":

Now you need to exchange the variable "x" with the variable "y". Then:

Finally, you get that the inverse of the function
is:
This matches with the option B.
I took 400 - 150 divided by 15 and got 16. So believe that should could afford to bring 16 people.
