inverse of f(x)=2sqrt(-5x-3)-2

inverse

f (x) = 2 - 5 x - 3 - 2

- \frac{4 x + x ^{2} + 16}{20}

Solution steps

y = 2 - 5 x - 3 - 2

Replace

x

with

y

x = 2 - 5 y - 3 - 2

Solve for

y, x = 2 - 5 y - 3 - 2

- \frac{4 x + x ^{2} + 16}{20}

f (x) = \frac{13}{x} + 7

y = 3 e^{2 x}

f (x) = - x^{2} + 3, x \geq 0

35

sin (4) x^{4}
