Answer:
35 seconds
Step-by-step explanation:
if you simply minus 7 seconds from max 42 second time you get 35 seconds.
-2x+3=15
Subtract 3 from both sides:
-2x=12
Divide -2 from both sides:
X=-16 is your answer
Answer:
F(x) and g(x) are not inverse functions.
Step-by-step explanation:
In order to calculate the inverse function of a function, we have to isolate X and after that, we change the variables.
As our function f(x) is a exponentian function, we can apply logarithm with base 10 (log) in both sides in order to isolate X. Remember that log10=1.

Now we change the variables.

F(x) and g(x) are not inverse functions.
