Plotting linear graphs Going from rule to graph. To sketch a linear graph from a rule, determine two points that satisfy the rule and connect them with a straight line. Two commonly used methods are: ...

In such cases a non-linear function must be used. Non-linear means the graph is not a straight line. The graph of a non-linear function is a curved line. A curved line is a line whose direction ...

Linear functions are known for their straight line graphs, while exponential functions show a rapid increase or decrease in values. To help students build their knowledge and understanding of these ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 ...
