Prove that f(x)=x+3/2 and g(x)=2x-3are inverse
goldfiish [28.3K]

Answer:

Proofs

Step-by-step explanation:

f(x) = x +  \frac{3}{2}

y = x +  \frac{3}{2}

x = y +  \frac{3}{2}

x -  \frac{3}{2}  = y

{f}^{ - 1} (x) = x -  \frac{3}{2}

They are not inverse because f^-1(x) = x - 3/2 is not the inverse to g(x) = 2x - 3.
