I feel empty inside so here's free points

When turned about its axis of rotation, which shape could have created this three-dimensional object?

Which equation represents a direct linear variationa. y=x2b. y=2/5xc. y=1/xd. y=x+3

Shape a is congruent to shape , as shown by a reflection across the y-axis and then a translation down units. shape b is congruent to shape , as shown by a reflection across the y-axis and then a translation down units.
