If you could explain and show your work towards finding the solution that would be awesome:

(d) (3 points) Provide a geometric argument that uses the area of rectangles to explain completing the square: ' + ar = (@+ ;)? - (@) . An accurate picture with labels will suffice.(e) (3 points) Are both of the following statements true? Explain. . Every polynomial is the sum of power functions. . Every sum of power functions is a polynomial.(f) (3 points) Fill in the blank (no work). The of a function f is denoted by f . In order for f- to exist the function f must be which can be seen graphically as the line test.(g) (3 points) Let f(x) be a degree 5 polynomial. The following table describes some of the outputs for f(I). -3 0 3 4 10 f(I) 0 3 -1 -10 -3 23 Using the information above, what can you say about the number of zeros of f(I)? Explain
