Which function is a quadratic function? f(x) = 2x2 g(x) = 5x3 k(x) = –x b(x) = –9x4

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

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)
