Answer:

Graph represented by option D is the correct choice.

Step-by-step explanation:

We have been given that a parabola has a minimum value of 0, a y-intercept of 4, and an axis of symmetry at $x=-2$ .

Since the minimum value of our given parabola is 0, so y-coordinate of vertex of parabola would be 0. This means that vertex of parabola will be at x-axis.

Since Since the minimum value of our given parabola is 0, so our parabola will be upward opening.

We are also told that parabola has an axis of symmetry at $x=-2$ . This means that parabola will be symmetric about line $x=-2$ .

The y-intercept of parabola is 4. This means that parabola will intersect y-axis at point $(0,4)$ .

Upon looking at our given choices, we can see that option D is the correct choice as it meets all the given conditions.

Inspired by the works of Neil Dawson and Bert Flugelman, Kassidy drafts a design for a modern sculpture, the amount of steel Kassidy will need is mathematically given as

SA=16.094711 ft^2

<h3>What is the amount of steel Kassidy will need to create the sculpture if the base of the sculpture is 4-feet tall and has a 2-foot diameter.?</h3>

Generally, the equation for the surface area of a cone is mathematically given as

SA=πr(rπ+√(h^2+r^2))

Therefore

SA=πr(rπ+√(h^2+r^2))

SA=π*1(1+√(4^2+1^2))

SA=16.094711 ft^2

In conclusion, the amount of steel Kassidy will need is

SA=16.094711 ft^2
