Answer: x=-5 or x=2
Step-by-step explanation:
x^2+3x-10=0
x^2+5x-2x-10=0
x(x+5)-2(x+5)=0
(x+5)(x-2)=0
x+5=0 or x-2=0
x=-5 or x=2
Go to the left-most point on the graph. That point is (-3,-2). The x coordinate of this point is x = -3.
So the smallest x can be is x = -3. The variable x can't be any smaller. It can be larger than -3.
Since x can equal -3 or be larger, this makes the domain to be

(x is
greater than or equal to -3)
In interval notation, you would write

The square bracket tells you to include the endpoint -3 while the curved parenthesis tells you to exclude infinity as an endpoint. Plus or minus infinity is always associated with a curved parenthesis.
In short,
the answer is choice D
