inverse of f(x)=sqrt(49-x^2)

inverse

f (x) = 49 - x^{2}

- x^{2} + 49, - - x^{2} + 49

Solution steps

y = 49 - x^{2}

Replace

x

with

y

x = 49 - y^{2}

Solve for

y, x = 49 - y^{2}

- x^{2} + 49, - - x^{2} + 49

f (x) = 4^{x} + 2^{x + 1} + 3

f (x) = 4 x^{2} - 25

f (x) = ln (5 x + 3)

f (x) = 4^{x + 3} - 2

f (x) = \frac{x}{25}
