For the function f(x)=10(x+7), find f−1(x)f −1 (x)

result is  xx/100 - (7/5)x  + 49    or.

f−1(x)f −1 (x) =  ((x/10) - 7)*((x/10) - 7)

Step-by-step explanation:

for the function f(x)=10(x+7), find f−1(x)f −1 (x)

f-inverse...

x = 10(y + 7)

(x/10) = y + 7

y = (x/10) - 7

f-inverse =  (x/10) - 7

then

f−1(x)f −1 (x) =((x/10) - 7)*((x/10) - 7)

xx/100 + 49  - (7/5)x

result is  xx/100 - (7/5)x  + 49

step-by-step explanation:

use a calculator!

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
