Helpppppp pleaseeeeee !!!!!!!!! !!!!

Given:

The function is:

$f(x)=6x-3$

To find:

The inverse of the given function, then draw the graphs of function and its inverse.

Solution:

We have,

$f(x)=6x-3$

Step 1: Substitute $f(x)=y$ .

$y=6x-3$

Step 2: Interchange x and y.

$x=6y-3$

Step 3: Isolate variable y.

$x+3=6y$

$\dfrac{x+3}{6}=y$

Step 4: Substitute $y=g(x)$ .

$\dfrac{x+3}{6}=g(x)$

Therefore, the inverse of the given function is $g(x)=\dfrac{x+3}{6}$ and the graphs of these functions are shown below.

How to find compound rate from given values, 10 years after, and initial

dybincka [34]

The formula that calculates the compound rate from the given values is $r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

<h3>How to determine the compound interest rate?</h3>

The compound interest formula is:

$I = P(1 + \frac rn)^{nt} - P$

Where:

P represents the principal amount
r represents the compound interest rate
n represents the number of times the interest is compounded
t represents the time in years
I represents the interest

We start by adding P to both sides

$P + I = P(1 + \frac rn)^{nt}$

Divide through by P

$\frac{P + I}{P} = (1 + \frac rn)^{nt}$

Take the nt-th root of both sides

$\sqrt[nt]{\frac{P + I}{P}} = 1 + \frac rn$

Subtract 1 from both sides

$-1 + \sqrt[nt]{\frac{P + I}{P}} = \frac rn$

Multiply through by n

$r = n(-1 + \sqrt[nt]{\frac{P + I}{P}})$

In this case, t = 10

So, we have:

$r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

Hence, the formula that calculates the compound rate is $r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$
