Step-by-step explanation:

tan 45° = 1

so,

4tan 45° = 4*1

i believe the correct answer is b.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
