Answer:

The graph is missing, but we can draw and describe each option.

<h3>Choice 1</h3>

y=3x

This is a linear function which passes throuhg the origin of the coordinate system because it doesn't have the constant b which is the y-intercept of the line.

The first image attached shows this function.

<h3>Choice 2</h3>

y=3x^{2} +1

This is a quadratic function. Its graph belongs to a parabola, all quadratic functions are represented by a parabola. In this case, the parabola has a vertex at (0,1). The second image attached shows this function.

<h3>Choice 3</h3>

y=3x-1

This is also a linear function, which is parallel to the first function, because they have the same slope of 3. But this one has y-intercept at (0,-1). The third image attached shows this function.

<h3>Choice 4</h3>

y=3x+1

This is also a linear function parallel to function 1 and function 3. The fourth image attached shows its graph. In this case, the line has y-intercept at (0,1).
