In summary, the equation of y=x^3-x^2+x-1 after being reflected in both the y-axis and x-axis is y=-x^3+x^2-x+1.

I'm not sure how to find the equation of y=x^3-x^2+x-1 after it is reflected in both the y-axis and x axis. Thank you!

reflection of $f(x)$ over the y-axis is $f(-x)$

reflection of $f(x)$ over the x-axis is $-f(x)$

so, $-f(-x)$ will do both ...
