Solve simple linear-quadratic systems algebraically and graphically.
Estimate line-parabola intersections from a graph
Problem
Use the displayed graph of \(y=x^{2}\) and \(y=2\). Estimate both intersection ordered pairs to the nearest tenth; then report the \(x\)- and \(y\)-reading for each.
Each graph intersection shares both coordinates. We’ll locate both crossings, read x horizontally and y vertically using the displayed scales, and use the equation x squared equals two as a numerical check before rounding both ordered pairs to the nearest tenth.
