It shows calculating quadratic values by substitution (for example 0 squared plus 0 minus 4 equals minus 4, and 3 squared plus 3 minus 4 equals 8), plotting points carefully on tricky scales, and joining them with a smooth curve. It then discusses identifying graphs such as x cubed and matching reciprocal graphs, plus estimating where equations like x squared minus x equal 4 and completing point plots for another quadratic. The Loom also covers solving a pair of sequence formulas by comparing common nth terms, finding an nth term for an arithmetic sequence with a difference of 6, and working with inequalities on a number line and greatest integer values."}
