How to inverse this function step by step <br> f(x)=x-3/5
Nitella [24]

f(x)=x3−5

Replace f(x)

with y

.

y=x3−5

Interchange the variables.

x=y3−5

Solve for y

.


Since y

is on the right side of the equation, switch the sides so it is on the left side of the equation.

y3−5=x

Add 5

to both sides of the equation.

y3=5+x

Take the cube root of both sides of the equation to eliminate the exponent on the left side.

y=3√5+x

Solve for y

and replace with f−1(x)

.


Replace the y

with f−1(x)

to show the final answer.

f−1(x)=3√5+x

Set up the composite result function.

f(g(x))

Evaluate f(g(x))

by substituting in the value of g into f

.

(3√5+x)3−5

Simplify each term.


Remove parentheses around 3√5+x

.

f(3√5+x)=3√5+x3−5

Rewrite 3√5+x3

as 5+x

.

f(3√5+x)=5+x−5

Simplify by subtracting numbers.

.

Subtract 5

from 5

.

f(3√5+x)=x+0

Add x

and 0

.

f(3√5+x)=x

Since f(g(x))=x

, f−1(x)=3√5+x is the inverse of f(x)=x3−5

.

f−1(x)=3√5+x

Graph this function
galben [10]
Solve the equation to get values for x and y.

For example,

When x is 0,

y = 1

You have one point on the line (0,1)

Now, when y = 0,

x = 36/5 = 7.2

You have one more point on the line (7.2,0)

Plot these points on the x and y axes.

Draw a straight line joining these two points. ( I hope you can plot the points)

A circular plot of land has a diameter of 16 yards. What is the area of theland? Use 3.14 for it.O A. 803.84 yd2O B. 50.24 yd2O
Amiraneli [1.4K]

The area of the circle can be calculated with the following formula

A=\pi\cdot r^2

First let's find the radius

\begin{gathered} r=\frac{16}{2}\text{yds} \\ r=8\text{yds} \end{gathered}\begin{gathered} A=\pi\cdot8^2 \\ A=3.14\cdot64 \\ A=200.96\text{ yd2} \end{gathered}

The answer would be 200.96 square yards

nalin [4]

Answer:

36

Step-by-step explanation:

Note that if there are two of the same number multiplied within a root, it becomes a whole number

√18 x √18 = 18

Next, simplify √4.  Factor the number:

√4 = √(2 x 2) = 2

Multiply: 18 x 2 = 36

36 is your answer
