Answer:
The number of x-intercepts of the function are:
Two(2)
Step-by-Step 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)
