-- The amount of the decrease is ($120 - $96) = $24

-- As a decimal of the original price, the amount is

$24 / $120 = 0.20 of the original price .

-- To turn any decimal into a percentage,
move the decimal point two places that way ===> .

0.20 = 20 %

The price was decreased by 20% of the original price.

Given the function f(x) = 3x, find the value of f−1(81).

Shalnov [3]

Given the function f (x) = 3x, find the value of f-1 (81).
For this case, the first thing you should do is rewrite the function.
We have then:
y = 3 ^ x
From here, we clear the value of x:
log3 (y) = log3 (3 ^ x)
log3 (y) = x
Then, we rewrite the function again:
f (x) ^ - 1 = log3 (x)
Now, we evaluate the inverse function for x = 81:
f (81) ^ - 1 = log3 (81)
f (x) ^ - 1 = 4
Answer:
the value of f-1 (81) is:
f (x) ^ - 1 = 4
