GRAPHING LINEAR AND NONLINEAR SYSTEMS A-CED.2 CREATE EQUATIONS IN TWO OR MORE VARIABLES TO REPRESENT RELATIONSHIPS BETWEEN QUANTITIES; GRAPH EQUATIONS ON COORDINATE AXES WITH LABELS AND SCALES. A-REI.11 EXPLAIN WHY THE X-COORDINATES OF THE POINTS WHERE THE GRAPHS OF THE EQUATIONS Y = F(X) AND Y = G(X) INTERSECT ARE THE SOLUTIONS OF THE EQUATION F(X) = G(X); FIND THE SOLUTIONS APPROXIMATELY, E.G., USING TECHNOLOGY TO GRAPH THE FUNCTIONS, MAKE TABLES OF VALUES, OR FIND SUCCESSIVE APPROXIMATIONS. INCLUDE CASES WHERE F(X) AND/OR G(X) ARE LINEAR, POLYNOMIAL, RATIONAL, ABSOLUTE VALUE, EXPONENTIAL, AND LOGARITHMIC FUNCTIONS.

TYPES OF EQUATIONS Nonlinear –Absolute Value –Square Root –Quadratic –Circle –Logarithmic –Exponential –Polynomial

STEPS FOR CALCULATOR Type equation into y = Press GRAPH to view the graph Press 2 ND GRAPH to view the table of points Plot points on a graph

ABSOLUTE VALUE

SQUARE ROOT

QUADRATIC

CIRCLE

GRAPHING SYSTEMS OF EQUATIONS Solution to a system is the point where the two equations intersect If the equations do NOT intersect, there is no solution

EXAMPLES

FINDING INTERSECTION IN CALCULATOR Type one equation into y1 and the other equation into y2 GRAPH 2 ND TRACE #5 Move the blinking cursor to the intersection using left and right arrow keys Press ENTER 3 times
