Answer:
8
Step-by-step explanation:
Mode is the number that repeats itself the most in data, because 8 contains the most X's, it is the mode
Answer:
The last one is the answer
Step-by-step explanation:
Answer:
y = 3x - 1
Step-by-step explanation:
Rise over run, so 3 over 1 = 3. The y-intercept is -1, so b = -1.
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:
x^2+4x
