Answer:

Step-by-step explanation:
We can use the definition of inverse functions. Recall that if two functions, <em>f</em> and <em>g</em> are inverses, then:

So, we can let <em>j</em> be the inverse function of <em>h</em>.
Function <em>h</em> is given by:

Find its inverse. Flip variables:

Solve for <em>y. </em>Add:

Hence:

Therefore, <em>a</em> = 1/3 and <em>b</em> = 2/3.
We can verify our solution:

And:
