Answer:

The number of x-intercepts of the function are:

Two(2)

Explanation:

The domain of a quadratic function is all real numbers and the range is y ≤ 2.

i.e. the graph of this quadratic polynomial will be a downward parabola whose vertex has y-coordinates less than or equal to 2.

Also we know that any upward or downward facing parabola have two x-intercepts i.e. the parabola crosses the x-axis at two points i.e. the y-coordinates of those two points are zero.

Hence, the number of x-intercepts of the function is:

Two(2)
