Question

find a formula for the inverse of the function
f(x)=sqr 10-3x

Answer 1

square both sides :

f(x)^2 = 10 - 3x
3x = 10 - f(x)^2
x = (10-f(x)^2)/3

let f-1(x) be the inverse of f(x) so :

f-1(x) = (10-x^2)/3

Answer 2

f(x)^2 where is from

Answer 3

sqaure both sides i wrote it in the first line

Answer 4

the question is f(x)= SQR root 10-3x

Answer 5

right ..
and now if you square both sides (raise to the power of 2)
you get
f(x)^2 = 10 -3x

Answer 6

f(x)10-3x

Answer 7

\[f(x) = \sqrt{10-3x}\]
square both sides and get :
\[{f(x)}^2 = 10-3x\]

Answer 8

i thing some is wrong

Answer 9

any way thanks for help

Answer 10

nothing is wrong ..

sqrt(a) = b
if you square both sides you get
a = b^2

same as
sqrt(25) = 5
square both sides you get
25 = 5^2
25 = 25

Answer 11

i know but the question is f(x)=10-3x Sqr

Answer 12

\[f(x) = \sqrt{10-3x}\]

Answer 13

like this ?

Answer 14

no

Answer 15

\[f(x) = {(10-3x)}^2\]
like this ?

Answer 16

find formula for the inverse of the function
f(x)=
