Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function.

y = 2x2 + 4

a. x=-1; (-1,6)
b. x= 0; (0,4)
c. x=0; (0,6)

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.

the answer is 31.27mph
