Help me

Use the function: f(x) = x^3 + 2

To determine if the function has an inverse you could:
Select one:
a. Switch the x and y variables then solve for y in the new equation
b. Graph the equation and apply the Horizontal Line Test
c. Both A and B
d. A only

Graph the equation and apply the horizontal line test ( method 1)

.....

You could also test for f(-x) = f(x) ( Even) otherwise odd.
