X^2-x-11=-x-7
X^2-11=-7
X^2=4
X=2 (4 was reduced to 2 after the equation was square rooted)

Answer:
The domain is -7, 0, and 5
The range is -1, 0, and 8
Step-by-step explanation:
The domain of a set of points is the x-value. In this case the x-values are -7, 0, and 5 respectively. The range of a set of points is the y-value so in this case the range is -1, 0, and 8.
The constant of proportionality is <em>4 .</em>
The equation is [ <em>Height = (4) times (Days)</em> ] .
When the sunflower is 60cm tall, 60 = (4) times (Days).
Divide each side of the equation by 4: <em>15 = Days</em>
