WAEC REVISION – Algebraic Graphs, Relations and Functions

Improve Competency with MyMathsHero

Special relations where every x-value (input) corresponds to exactly one y-value (output) are called functions. We can easily determine whether or not an equation represents a function by performing the vertical line test on its graph.

 In this topic, we cover the following: Linear graphs, linear programming, quadratic graphs, sketch graphs and relations & functions. At the end of this topic, students should understand the following among other things:

  • How to solve quadratic equations using factorization, completing the square, the quadratic formula, and graphical methods,
  • Transform word problems into quadratic and linear equations that may be solved algebraically,
  • Use algebraic and graphical methods to solve simultaneous linear and quadratic equations.
  • Be able to use various expressions for the gradient of a straight line,
  • Able to find the intercepts that a line makes with the x- and y- axes and use them to draw the line,
  • Find the distance between two points and also find the coordinates of the midpoint of a straight line joining two points on the Cartesians plane,
  • Calculate the angle between two lines on the Cartesian plane and be able to use the conditions for two lines to be ‘a ‘parallel, ‘b’ perpendicular.
  • Show on a graph the region which contains the solutions of the simultaneous inequalities,
  • Represent various inequalities on a separate number line and draw the graphs of various linear equations on separate axis
