Question

define linear and quadratic function

Answer 1

linear function - a mathematical equation in which no independent variable is raised to a power greater than one and some variables are necessarily in the first exponent. A simple linear function with only one independent variable(y = a + bx) traces a straight line when plotted on a graph. Also called linear equation.

quadratic function - a mathematical equation in which no independent variable is raised to a power greater than two and some variables are necessarily in the second exponent. A simple quadratic
function with only one independent variable(y = ax² + bx+c) traces a parabola when plotted on a graph. Also called quadratic equation.
