1.Let f:R→Rf: \mathbb{R} \to \mathbb{R}f:R→R be a function defined by f(x)=x(1+x4)1/4f(x) = \frac{x}{(1+x^4)^{1/4}}f(x)=(1+x4)1/4x, and g(x)=f(f(f(f(x))))g(x) = f(f(f(f(x))))g(x)=f(f(f(f(x)))). Then 18∫025x2g(x) dx18 \int_0^{\sqrt{2\sqrt{5}}} x^2 g(x) \, dx18∫025x2g(x)dx is equal to:Login to continueOnly logged in users canattempt or see the solution.
