Question

y=f(x)=2x-3÷3x-2.findf(y)​

Answer 1

Answer:

y = (2x - 3)/(3x - 2)

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

Substitute the value of y in the equation :

⇒ f(y) = [ 2(2x - 3)/(3x - 2) - 3 ] / [ 3(2x - 3)/(3x - 2) - 2 ]

⇒ f(y) = [ (4x - 6 - 9x + 6 )/(3x - 2)] / [ (6x - 9 - 6x + 4)/(3x - 2)

⇒ f(y) = [ -5x ] / [ -5 ]

⇒ f(y) = x
