The function models the depth of a submarine, where y = 0 is at sea level. Over what interval is the submarine rising? x y = –2x2 (x, y) –3 –18 (–3, –18) –1 –2 (–1, –2) 0 0 (0, 0) 1 –2 (1, –2) 3 –18 (3, –18) A. x < –2 B. x < –1 C. x < 0 D. x > 1

For which rational expression is -2 an excluded value of x?

If given an equation of a line such as -1/2x+6 how would you create an equation of a line parallel and perpendicula to this line that goes through another point such as (4,10)

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
