Answer:

Yo

So, if ya wanna solve this question and of course questions alike, ya gotta pay attention to the graph. mean All of these parabolic chart have the domain of R

Explanation:

So there ya go

D=R

and now bout the range ya gotta find the vertex, which is:


x = ( - b)/(2a) \: \: y = (Δ)/(4a)

now pay attention

X=2/–2=–1

y=–(–1)²–2(–1)+3=4

Now the highest point of your parabolic chart is 4 and the lowest point is endless which is (–♾,4]

Well, finally your answer is D
