Find all numbers \(a\) for which the graph of \(y=x^{2}+a\) and the graph of \(y=ax\) intersect. Express your answer in interval notation.
The set of all a that works is [4,inf).
please explain. And are there any possible negative values
Actually, I got the correct answer, its (-inf, 0] \cup [4, inf)
