If a graph intersects the x-axis at (-12, 0) and (-4, 0), which zero is greater?
Answer and explanation
Correct answer: -4
The zeroes of a polynomial are the x-coordinates where its graph meets or cuts the x-axis. Here, the zeroes are -12 and -4. On the number line, -4 lies to the right of -12, so -4 is greater. Equivalently, among negative numbers, the number with the smaller absolute value is greater. Therefore, option B is correct; 0 and 12 are not the given zeroes.
