Answer:

(2, - 9 )

Step-by-step explanation:

Since 2 is the output when - 9 is input to f(x)

Then reversing the procedure, that is the inverse gives an output of - 9 for an input of 2.

(- 9, 2) is a point on the graph of f(x), then

(2, - 9) is a point on the graph o the inverse function $f^{-1}$ (x)

Answer:

$225

Step-by-step explanation:

Given that:

Principal = $6,000

Interest rate = 5%

Time = 1 year

Taxes paid = 25% on the interest earned

To find:

Money earned after paying taxes ?

Solution:

First of all, let us calculate the total interest earned:

Formula for Simple Interest is given as:

$SI =\dfrac{PRT}{100}$

Where P is the principal

R is the rate of interest

T is the time taken

Putting the given values:

$SI =\dfrac{6000 \times 5\times 1}{100} =\$300$

Now, it is given that 25% of the interest earned is given as taxes.

Taxes paid = 25% of $300

$\Rightarrow \dfrac{25}{100} \times 300 =\$75$

Therefore, the money earned = Interest earned - Taxes paid

The money earned = $300 - $75 = $225
