Question

find the inverse of f(x)= 2x^2-3

Answer 1

give its verification

Answer 2

@ganeshie8 pls help

Answer 3

put y=2x^2-3
y+3=2x^2
y+3/2=x^2
rt(y+3/2)=x
now put x in place of y and y in place of x
f(x)=rt(x+3/2)

Answer 4

@Faye281 is the answer ryt

Answer 5

ty @Faye281

Answer 6

yes but my question is how dod you get the answer the verification

Answer 7

f(f^-1(x)) and f^-1(f(x))

Answer 8

what is rt? sqaure root? @ajaysagar

Answer 9

yes

Answer 10

the verification @ajaysagar

Answer 11

keep the above value in f(x)
put f(rt [x+3]/2)
you get
f(rt [x+3]/2) =2*(x+3)/2-2
you get x
