P.S. Can you help with my problem? The polynomial f(x) has degree 3. If f(-1) = 15, f(0)= 0, f(1) = -5, and f(2) = 12, then what are the x-intercepts of the graph of f?
infinite solutions i think
First number = x
second number = x-3
third number = 2x
x + x-3 + 2x = 53
4x -3 =53
4x -3+3 =53+3
4x = 56
4x/4 = 56/4
x = 14
first number = 14
second number = 14-3
second number = 11
third number = 2x
third number = 2(14)
third number = 28
14 + 11 +28 = 53
53=53
