Answer:

b.  x = 0 ; (0,4)

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.

Please see the attached image below, to find more information about the graph .

The equation is:

y=2*x^2+4

We can appreciate that the axis of symmetry corresponds to the y-axis, which  is equal to the line x = 0

The vertex corresponds to the minimum point of the function.

V = (0,4)

Correct option: b.

Answer:

x = 0; (0, 4)

Step-by-step explanation:

x =  −b/2a  =  0/2(2)  = 0

The axis of symmetry is x = 0.

y = 2x2 + 4

y = 2(0)2 + 4 = 4

The vertex is (0, 4).
