Question

Select the correct answer.

The vertex of a parabola is at the origin, and its focus is at
`(0, 1/8)`. Which function does the graph with these attributes represent?

A.
`f(x)=2x^2\\`

B.
`f(x)=2(x+1)^2`

C.
`f(x)=2(x-1)^2`

D.
`f(x)=-2x^2`

Answer 1

A. f(x)=2x^2

Explanation:

Graphing this equation shows us that its vertex is at the origin (0,0) and by solving and refining for the focus of the parabola gives us (0,1/8) which fits the criteria the question is asking for.
