Answer:
2
Step-by-step explanation:
We know that the graph of a quadratic function is a parabola with both ends going to either positive or negative infinity if there's no limit on the domain. In this case the range is y ≤ 2, so we know that the vertex of the parabola is at 2 and that the ends go to negative infinity. Therefore each end has to cross the x axis, giving us two x-intercepts.
The number of x-intercepts that the quadratic function has is 2.
A quadratic function simply means a polynomial function with one or more variables where the highest exponent of the variable is two.
In this case, the graph of a quadratic function is a parabola. Here, the range is y ≤ 2, therefore, we know that the vertex of the parabola is at 2. Also, the ends go to negative infinity. Therefore, the number of x-intercepts that the quadratic function has is 2.
