To find the inverse of a function, first make f(x) a y
So,
y = 
-18
Then switch the x and the y
x = 
- 18
Solve, for y
D : 0.300- 0.006 is correct
A is wrong bec 0.3 doesn’t have the extra 0’s in the end
B is wrong bec the decimal places aren’t aligned
C is wrong bec again, the decimal places aren’t aligned
To determine the percent change in price, solve for the differences between the original prices and the sale prices. Then, divide the difference by the original price and multiply by 100%.
Guitar 1: (($160 - $100) / $160) x 100% = 37.5%
Guitar 2: (($250 - $150) / $250) x 100% = 40%
Thus, guitar 2 has a greater percent change in price.
