Answer:
yes
Step-by-step explanation:
f(x) = 2x³ -
x² - 4x + 6
g(x) =
( 4x³ - 3x² - 8x + 12) ← multiply each term in the parenthesis by 
= 2x³ -
x² - 4x + 6
= f(x)
Then f(x) and g(x) are equal polynomials
Explanation:
For a function ...
y = f(x)
the inverse function is ...
x = f(y)
To write that in the form y=f^-1(x), you need to solve for y.
__
For your function f(x) = e^x +3 this looks like ...
x = e^y +3
x -3 = e^y . . . . . subtract 3
ln(x -3) = y . . . . . take the natural log
So, we can write ...
f^-1(x) = ln(x -3)
_____
Attached is a graph of these functions. As you might guess from the interchange of x and y, a function and its inverse are mirror images of each other across the line y=x.
