Question

The domain of a quadratic function is all real numbers and the range is ys 2. How many x-intercepts does the

function have?

Answer 1

2 x-intercepts if range is y < 2

Explanation:

If this quadratic function has a range y < 2, then definitely this function can have x-intercepts at y =0, therefore there are 2 x-intercepts

However if range is y > 2, then there are 0 x-intercepts.
