as such all linear equations will be functions because there can only be 1 and only 1 value of y for each value of x. there is, i believe, one major exception. the equation of x = c is a linear equation because it is an equation of a straight line. this equation is not a function because you can have more than 1 value of y for each value of x. A linear function is an algebraic equation in which each term is either: a constant (just a number) or. the product of a constant and a single variable that has no exponent (i.e. that is to the power of 1) The graph of a linear function is a straight line. For example, the function: y = x is a linear function.. A linear function is one of the form y = mx + c. For each input of x, you get one output for y. The graph of these functions is a single straight line. A quadratic function is one of the form y = ax2 + bx + c. For each output for y, there can be up to two associated input values of x. A quadratic equation can be factorised in order to find its roots. The roots of a quadratic equation are the values of which make the equation equal to 0. They also represent the two places on the function that intersects the -axis. Thus, “solving” a quadratic equation means finding its roots.
