WHAT WOULD THE INVARIENT BE FOR THIS PROBLEM? 10 PTS.!!! MATH....read?

Question

SAYS;

Determine the inverse functions for the functions below. Begin by switching varaiables in the original function, then solving for the 'new' y. For each case sketch the function and its inverse.

Have no idea what this is or what to do. Please explain how u found answer. 10 Points! :)

3. y= (2/3)x - 4

What is the invariant?

Answer 1

exchange the variables and solve for y

x= (2/3)y - 4

(2/3)y = x + 4

y = (3/2)x + 6

is the invariant the degree of the polynomial? in this case it is 1.
