Question

2 y -10-8-6-4-2 0 2 t-2- -4- -6° t-8- 10 4 6 8 10 -X An equation of the parabola shown in the xy-plane is y = ax² - c, where a is a constant and c is an integer. What is the value of c?​

Answer 1

The vertex of the parabola is at (0, -10), and since the equation is in the form y = ax² - c, the value of c is the y-coordinate of the vertex, which is -10. Therefore, the value of c is -10.
