Jika f (x) = 3x+4/2x-5,x¥ 2/5 ,maka f -1 (x)= …tolong jawad ya pliss

Jawab:

Penjelasan dengan langkah-langkah:

$sf gunakan rumus :\\\boxed{sf f(x)= dfrac{ax+b}{cx+d} to f^{-1} (x) = dfrac{dx-b}{-cx+ a} atau f^{-1} (x) = dfrac{-dx+ b}{cx- a}}$

$sf f(x)= dfrac{3x+4}{2x-5}\\\f^{-1} (x) = dfrac{-5x-4}{-2x + 3} \\\ f^{-1} (x) = dfrac{5x + 4}{2x - 3}$
