inverse of f(x)=sqrt(4x^4+7x^2)

Solution

inverse

f (x) = 4 x^{4} + 7 x^{2}

Solution

\frac{2 - 7 + 49 + 16 x ^{2}}{4}, - \frac{2 - 7 + 49 + 16 x ^{2}}{4}, \frac{2 - 7 - 49 + 16 x ^{2}}{4}, - \frac{2 - 7 - 49 + 16 x ^{2}}{4}

Solution steps

y = 4 x^{4} + 7 x^{2}

Replace

x

with

y

x = 4 y^{4} + 7 y^{2}

Solve for

y, x = 4 y^{4} + 7 y^{2}

\frac{2 - 7 + 49 + 16 x ^{2}}{4}, - \frac{2 - 7 + 49 + 16 x ^{2}}{4}, \frac{2 - 7 - 49 + 16 x ^{2}}{4}, - \frac{2 - 7 - 49 + 16 x ^{2}}{4}
