One root of the quadratic equation whose related function is graphed lies between which consecutive integers?
-
-4 and -3
-
0 and 1
-
-5 and -4
-
-3 and -2
Correct Answer
A. -4 and -3Explanation
The correct answer is -4 and -3 because the graph of a quadratic function intersects the x-axis at the x-coordinate(s) of its roots. Since the question states that one root lies between -4 and -3, it means that the graph intersects the x-axis between these two consecutive integers.Rate this question:

-
{5, 11}
Correct Answer
A. {5, 11}Explanation
The zeros of a function are the values of x for which the function equals zero. In this case, the zeros of the function are 5 and 11, as these are the values of x that make the function equal to zero.Rate this question:

Find the x-intercepts in the function
-
{7, 8}
-
{-7, -8}
-
{-7, 8}
-
{7, -8}
Correct Answer
A. {7, 8}Explanation
The x-intercepts of a function are the points where the graph of the function intersects the x-axis. In this case, the x-intercepts are given as {7, 8}. This means that the function crosses the x-axis at the points (7, 0) and (8, 0).Rate this question:
