Plzz help I have a time test

Which of the following is the missing term, a2, of the geometric sequence in which a1=2 and a3=200

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 4x^2 - 19x- 5

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
