Question

Can someone please help me with this​

Answer 1

Step 1) The vertex of the parabola is (0,2). Thus, the vertex formula a-(h^2)/4a can be used.

Step 2) Plugging in the known vertex coordinates (0,2) into the vertex formula, we get:

2 = a - (0^2)/4a

2= a

Step 3) Therefore, the equation of the parabola is y = 2 - x^2

So the equation of the function is:

y = 2 - x^2
