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.
