Question 46: Given the function y=f(x). The graph of the function y=f'(x) is as shown in the figure below. The function \(y=f\left(x^{2}\right)\) is covariate on which of the following intervals?

Multivariable function \(y^{\prime}=2 xf^{\prime}\left(x^{2}\right)>0\)

With \(x>0 \Rightarrow f^{\prime}\left(x^{2}\right)>0 \Leftrightarrow\left[\begin{array}{l}-1

With \(x<0 \Rightarrow f^{\prime}\left(x^{2}\right)<0 \Leftrightarrow\left[\begin{array}{l}x^{2}<-1\\1
