Answer:
f(x) =
Step-by-step explanation:
The given options are,
a) f(x) =
b) f(x) =
c) f(x) =
d) f(x) =
Now, clearly a) is a monotonically increasing function, hence discarded, and both of c) and d) don't pass through (0, 1) hence they are also discarded.
Only b) is a decay function which does also pass through (0, 1), hence, b) is the correct option.
Answer:
Step-by-step explanation:
Twice the difference means:
the difference of a number and 9 means:
is at most 15 means:
Here's the method on the first one (36)
The ratio is
, hence if we call
the number below
, we will have
hence
