point of intersectionA point shared by two graphs, whether they cross, touch, or overlap there. Its coordinates, the numbers locating it, make both equations true at the same time.
You’ll leave with these skills
01Find the equation that fits every row of a tableType the table into Desmos, graph each answer choice, and pick the one that passes through every point.
02Match a function to the table of its outputsType the x-values into a Desmos table and type the function at the top of the next column so Desmos fills in every y-value.
03Spot the table whose rows all solve an inequalityGraph the inequality in Desmos, plot each table’s points, and keep the table whose points all land in the shaded region.
04Match a shifted function such as f(x − 2) to its tableType the shifted function as a column heading exactly as the question writes it, then compare that column with each answer choice.
