## anonymous 5 years ago Hi! Could someone please explain how to solve this problem? :) Find the range of the function f(x)=|x^2-3|-2 According to the answer key, the answer is [-2,∞) Thank you! <3

When you write a question, you don't have to write its answer :)

Anyway if you want to know how to get the answer, you need to first on the absolute value. The absolute value can only have values that are $$\ge0$$. So, the range of $$|{x^2-3}|$$ is $$[0,\infty))$$. Now when you subtract $$2$$ from that, your new range (the range of the given function would be $$[-2,\infty)$$.

Does that make sense?!
