Introduction: Quadratic equations can always be solved using the quadratic formula. It is ax squared plus bx plus c equals 0, where a does not equal 0.So it is x equals -b plus/min
Introduction: A quadratic equation is an equation of degree 2 that is in the form x squared plus bc plus c equals 0. If the equation can be factored, then we are able to find the r
Introduction: Solving inequalities are very important when we want to find the values of x where the function is positive or negative . Example 1: solve x squared – x –
Introduction: The domain of a relation and function are those values of x over which the function and relation is defined. The range are the y values over which the function and re
Introduction: A relation is any set of ordered pairs (x,y). Ex. x squared plus y squared equals r squared. This is the equation of a circle with center(0,0) and of radius r. A func
Introduction: The Pythagorean theorem for a right triangle of leg lengths an and b and hypotheses of length c is given by the formula a squared plus b squared equals c squared.. Th
Introduction: If an all cubed is a power of a, then 3 is the exponent and a is the base. The following laws of exponents hold true. Power of a power: a with exponent m raised to th
Introduction:The slope point form of the equation of a line is y – y1 equals m(x – x1) where m is the slope and (x1,y1) is a point on the line. Example 1: y -1 equals 3
Introduction: The slope of a line is a measure of how steep a line is. It is computed using the formula m equals y2-y1/x2-x1 where (x1,y1) and (x2,y2) are two points lying on the l
Introduction: A linear system of equations in x and y has three possible solutions. The two lines can intersect in a point (x,y) or they may be parallel with no intersection point
Introduction The slope y-intercept equation of a line is given by y equals Mx plus B where m is the slope and B is the y intercept. It is a linear function whose degree is 1. Its g
Introduction: A linear equation in one variable is an equation of degree 1. Example 1: 2x – 3 equals 12. To solve a linear equation means to find the x-intercept of the line
