<h3>How to solve percentage</h3>
From the information given, it was stated that there's a 10 percent on first $5,000 and 15% over $5,000.
The total graduate commission on $22,000 will be:
= (10% × $5000) + (15% × $17000)

Using the quadratic equation we get:

Factoring out 2 we get

Factoring out the imaginary number:

So b.
Let d(x) = 2x - 4
Or
y = 2x - 4
We have replace x = y
x = 2y - 4
Now Isolate "y"
x + 4 = 2y
Pass "2" dividing
(x + 4) / 2 = y
y = x/2 + 2
Or
d(x)^-1 = x/2 + 2
