For the following exercise, graph $$ y=x^2 $$on the given domain. Determine the corresponding range. Show each graph.
$[−10, 10]$ is not supposed to be the all real number?
Why when I found the answer in the answers section I found the answer is $[0,100]$?
They are asking you to look at the function $f(x)$ on the restricted domain of only values in $[-10,10]$. On these numbers, the smallest the output gets is $0=0^2$ and the largest is $100=10^2=(-10)^2$, and as the function is continuous it hits everything in between, thus on the restricted domain, you get the range is $[0,100]$
