riangle ABC, with A = (-2,3) B = (-4,1) and C = (-3,5), is rotated 90° clockwise about the origin to make Triangle A'B'C'. What are the y-coordinates of B'?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Which describes the difference between the graph of f(x)=x^2 and g(x)=-(x^2-2)
