What is the solution set of the quadratic inequality f(x) greater than or equal to 0
1 answer:
ANSWER
{}
EXPLANATION
From the graph, the given quadratic inequality is
We can see that the corresponding quadratic function is a perfect square.
Since the graph opens upwards and it is always above the x-axis, any real number you plug into the inequality, the result is greater than or equal to zero.
Hence the solution set is
