Use a graphing calculator to graph the original function y=12x−4 and the vertically dilated function with a factor k=6 . Determine the x-intercepts of both functions.(1 point) Responses The original function has an x-intercept of (−8,0), and the dilated function has an x-intercept of (−8,0). The original function has an x -intercept of left parenthesis negative 8 comma 0 right parenthesis , and the dilated function has an x -intercept of left parenthesis negative 8 comma 0 right parenthesis . The original function has an x-intercept of (8,0), and the dilated function has an x-intercept of (48,0). The original function has an x -intercept of left parenthesis 8 comma 0 right parenthesis , and the dilated function has an x -intercept of left parenthesis 48 comma 0 right parenthesis . The original function has an x-intercept of (8,0), and the dilated function has an x-intercept of (8,0). The original function has an x -intercept of left parenthesis 8 comma 0 right parenthesis , and the dilated function has an x -intercept of left parenthesis 8 comma 0 right parenthesis . The original function has an x-intercept of (0,−4), and the dilated function has an x-intercept of (0,−24)
The correct answer is:
The original function has an x-intercept of (-8,0), and the dilated function has an x-intercept of (-8,0).
