F(x) = 5x + 6

let y = f(x)

y = 5x + 6    solving for x.

y - 6 = 5x

5x = y - 6

x = (y - 6)/5

Recall   f(x) = y.   Implies  x = f⁻¹(y)

<span>x = (y - 6)/5
</span>
f⁻¹(y) <span>= (y - 6)/5
</span>
So as well:

f⁻¹(x) <span>= (x - 6)/5</span>

Jessica purchased a DVD that was on sale for 12% off.

The sales tax in her county is 3%.

Let, y represent the original price of the DVD.

We can simply solve this mathematical problem by using the following mathematical process.

Here, we will form an algebraic expression, according to the given data.

So,

The original price of the DVD = y

Discount on the original price :

y * 12/100

=3y/25

Price after discount :

y - 3y/25

=25y - 3y/25

=22y/25

Sales tax amount :

22y/25 * 3/100

11y/25 * 3/50

=33y/1250

Final price including the sales tax :

22y/25 + 33y/1250

1100y + 33y/1250

1133y/1250

(This will be considered as the final result.)
