inverse of f(x)=sqrt(1-21x^2)

inverse

f (x) = 1 - 21 x^{2}

- \frac{x ^{2} - 1}{21}, - - \frac{x ^{2} - 1}{21}

Solution steps

y = 1 - 21 x^{2}

Replace

x

with

y

x = 1 - 21 y^{2}

Solve for

y, x = 1 - 21 y^{2}

- \frac{x ^{2} - 1}{21}, - - \frac{x ^{2} - 1}{21}

f (x) = \frac{1 + 1}{( 1 + 0.15 \cdot 10 )}

f (x) = 2 (3 x + 1) + 4

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

f (x) = \frac{x - 2}{7}

e^{- y}
