Step-by-step explanation:
There are four important oceanic zones where plants and mammals survive in the ocean. The four significant zones are open ocean zone, intertidal zone, neritic zone, and benthic zone.There are four ocean zones. The sunlight zone, twilight zone, midnight zone, and abyssal zone.
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
Answer:
y=4
Step-by-step explanation:
y=2+2/2-1
y=4
