Answer:

1st q answer is f(x) is one- to -one function and 2nd q answer is 2

Answer:

1) f(x) is one - to - one function

2) 2

Step-by-step explanation:

inverse of f(x)

Let f(x) = y

y = 2x - 3

x = y + 3 / 2

inverse of f(x) = x + 3 / 2

g(x) = inverse of f(x)

f [g(2)]

f [2+3/2]

f [5/2]

(2×5/2)-3

5-3

= 2

Therefore f [g(2)] = 2
