Question

- The parabolas y = x² and y=-x² - 4x + 6 are graphed below. What are the y-values of the solutions to this system of equations? A: y = 1,6 B: y = 0,6C: y = -3, 1D: y = 1,9

Answer 1

Answer: D: y = 1,9

Explanation:

The given equations are

y = x^2

y = - x^2 - 4x + 6

On the graph, the solutions are the x and y coordinates of the point of intersection of the 2 graphs. The solutions(x and y coordinates) are

(1, 1) and (- 3, 9)

The y-values of the solutions to this system of equations is

D: y = 1,9
