Answer:
Step-by-step explanation:
All those words, when the math is so much clearer!
x = (9±√(9^2-4*1*5))/2 = (9±√101)/2
1 (B), because 3+-2=1, and 5+-4=1, which amounts to 1/1, or whole number 1.

Answer:
14. C
15. C
Step-by-step explanation:
14. The function is entirely in quadrants I and II, so the leading coefficient is positive. This eliminates choices A and B.
The horizontal asymptote is 0, not -1, eliminating choice D.
The curve is best described by the equation of choice C.
