Learning goals: Teacher Facing Compare key features of graphs of functions and interpret them in context. Interpret equations of the form $f(x)=g(x)$ in context and recognize that the solutions to such an equation are the $x$-coordinates of the points where the graphs of $f$ and $g$ intersect. Interpret statements about two or more functions written in function notation. Full lesson plan (warm-up, activities, synthesis, cool-down prompt) from Alg1.4 Functions, Algebra 1.
