Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
<h3>

</h3>
To solve the equation we must first find h-¹(x)
To find h-¹(x) equate h(x) to y
That's
<h3>

</h3>
<u>Next interchange the terms </u>
x becomes y and y becomes x
That's
<h3>

</h3>
<u>Make y the subject</u>
Take logarithm to base 2 to both sides
That's
<h3>

</h3>
But
<h3>

</h3><h3>

</h3>
So we have
<h3>

</h3>
Now we can solve the equation
We have
<h3>

</h3>
Convert the logarithm into exponential form using the fact that
<h3>

</h3>
So we have
<h3>

</h3>
But
<h3>

</h3>
So we have the final answer as
<h3>

</h3>
Hope this helps you
Add 5
y is found by adding 5 to x
