Answer:
C
Domain (-x,x): (-inf, inf)
Range (-y,y): [1, 0)
Step-by-step explanation:
Domain is -x to x which is the lowest x value marked to the parabola to the highest. Since their are arrows indicating that the parabola continues both ways, the domain is infinite both ways. The range has the endpoint of one and the continuation of 0 (you can tell by the brackets [], (), [), or (]; [ <- endpoint; ( or ) <- continuation), the range is [1, 0). :)
