Answer:
Step-by-step explanation:
So we have the function:
To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:
Add 9 to both sides:
Take the natural log of both sides:
The right side cancels:
Divide both sides by 6:
And we're done!

Answer:
$165
Step-by-step explanation:
Cost of dinner = $132
Sales tax = 10% of dinner cost
Tip left = 15% of dinner cost
Amount of sales tax :
10% of $132
0.1 * $132 = $13.2
Amount of tip left :
15% * $132
0.15 * $132 = $19.8
Total cost of dinner :
Dinner cost + sales tax + tip
$132 + $13.2 + $19.8
= $165
