a 95% confidence interval for difference in proportions p1-p2 if the sample have n1= 30 with p1 =0.72 amd n2 =100 with p2= 0.58 and the standar error is SE= 0.10

(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)
