Question

Question 22 OT Which of the following equations represents a parabola that opens down and has a vertex at (3,-1)? O A. y = -2(x - 3)2 - 1 O B. y = -2(x+3)2 - 1 C. y = 2(x-3)2 - 1 D. y = -2(x - 3)2 +1 x – SUBMIT PREVIOUS

Answer 1

Given data:

The options in the probelm.

The first option expression is,

`\begin{gathered} y=-2(x-3)^2-1 \\ (y+1)=-2(x-3)^2 \\ \end{gathered}`

Here, negative sign shows the parabola is oppen down and vertix is (3,-1).

Thus, first option is correct.
