10. nd the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y - 2x^2+6-1

The correct answer is C.

Step-by-step explanation:

To find the line of symmetry, we use the equation:

-b/2a

In this equation, a is the coefficient of x^2 and b is the coefficient of the x term.

-b/2a

-6/2(-2)

-6/-4

1.5

Now we know that 1.5 is the line of symmetry, which gives us C as the only possible answer.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
