I need help solving number 3. (A-E) please. Not sure how to even begin. Thank you

Step-by-step explanation:
Domain: (-infinity, infinity) This means x is never undefined
Range: (-infinity, infinity)
f(-10): -9
f(0) = 3
f(10) = 103
Graph the function bu plotting points and plugging the point into the first equation if it is less and -1 and plugging it into the second equation if x is less than or equal to -1.
