Kis a nonzero integer and the graph of a parabola "y = x² + 2kx + 4k" is tangent to the x-axis. what is the value of "k"? (a) - 4 (b) 0 (c) 2 (d) 4

(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)
