inverse of f(x)=60-4.9x^2

inverse

f (x) = 60 - 4.9 x^{2}

- \frac{10 x - 600}{49}, - - \frac{10 x - 600}{49}

Solution steps

y = 60 - 4.9 x^{2}

Replace

x

with

y

x = 60 - 4.9 y^{2}

Solve for

y, x = 60 - 4.9 y^{2}

- \frac{10 x - 600}{49}, - - \frac{10 x - 600}{49}

\frac{1}{x ^{2} + 1}

12 x + 4

12 x + 5

f (x) = x^{\frac{2}{5}} + 4

f (x) = (\frac{π}{3})
