If f(x)=3x, what is f^-1(x)?

  f-1(x) = x/3 + 5/3

Step-by-step explanation:                                                                                  The inverse function is found by replacing the independent variable with the dependent variable and vice versa like so

f(x) = 3x-5 becomes x = 3y-5; now we solve for y

3y = x +5 or y = x/3 + 5/3

Therefore the inverse function becomes: f-1(x) = x/3 + 5/3

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

answer: i think one of the answer is $150 and $300?
