Priya plots the temperature error of an experiment as y = p(x) and finds the curve, a parabola, lies completely below the x-axis. How many real zeroes does p(x) have, and what does that mean about p(x) = 0?

Question

Accepted Answer

0 zeroes; p(x) = 0 has no real solution. A parabola entirely below the x-axis never meets it, so p(x) is never 0; the equation p(x) = 0 has no real solution.

Priya plots the temperature error of an experiment as $y = p (x)$ and finds the curve, a parabola, lies completely below the $x$ -axis.
How many real zeroes does $p (x)$ have, and what does that mean about $p (x) = 0$ ?
