inverse of f(x)= 3/pi arccos(x)

inverse

f (x) = \frac{3}{π} arccos (x)

cos (\frac{x π}{3})

Solution steps

Solve for

arccos (x), y = \frac{3}{π} arccos (x)

arccos (x) = \frac{y π}{3}

arccos (a) = b \Rightarrow a = cos (b)

cos (\frac{y π}{3})

Substitute

y = x

cos (\frac{x π}{3})

y = \frac{5 x - 4}{2 x - 3}

3^{(x + 7)} + 2

f (x) = f (x) = - 8 - 5 x

+ \frac{z}{( z + 1 ) ^{2}}
