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

There are 12 students in a graduate class. The students are to be divided into three groups of 3, 4, and 5 members for a class p
exis [7]

Answer:

27720

Step-by-step explanation:

Given that there are 12 students in a graduate class. The students are to be divided into three groups of 3, 4, and 5 members for a class project.

From 12 students 3 students for group I can be selected in 12C3 ways.

Now from remaining 9, 4 students can be selected for II group in 9C4 ways

The remaining 5 have to be placed in III group.

Hence possible divisions for grouping the 12 students in the class into three groups

= 12C3 *9C4

= =220*126=27720

Consider function f and function g.
ivolga24 [154]

The statement the graphs of both functions have a vertical asymptote of x=0 and statement unlike the graph of function f, the graph of function g decreases as x increases are true.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have two functions:

f(x) = lnx

g(x) = -5 lnx

The domain of the both functions x > 0

The function will be touch the y-axis when x reaches to the infinite.

The graphs of both functions have a vertical asymptote of x=0.

Unlike the graph of function f, the graph of function g decreases as x increases.

The graph of function g is the graph of function f vertically stretched by a factor of 5 and reflected over the x-axis.

Thus, the statement the graphs of both functions have a vertical asymptote of x=0 and statement unlike the graph of function f, the graph of function g decreases as x increases are true.

wolverine [178]
First you have to find a common denominator which is 8.
1/2 =4/8
7/8 - 4/8 = 3/8
So the answer is 3/8.
