<h3>Right answer.</h3>
This is true because of the graph. As you can see, if x increases without bound, then f(x) take values from the <em>straight line </em>but those values become more and more negative. On the other hand, if x gets more and more negative, then f(x) approaches zero.
X2+y2–x–2y–11/4=x2−x+14−14+y2−2y+4−4−11/4=(x−12)2+(y−2)2−14−4−114=(x−12)2+(y−2)2−7=0(x−12)2+(y−2)2=(7√)2
Center(1/2 ,2)
radius = \sqrt 7
