Step-by-Step Solution:
Step 1 of 3

FUNCTIONS AND THEIR GRAPHS NOTES Pythagorean Theorem-  For a right triangle with hypotenuse c and length sides a and b.  Formula: a^2+b^2=c^2 Distance Formula-  To find the distance d between the points (x1,y1) and (x2,y2) in the plane.  Formula: d=√(x2 −x1)^2 +(y2 −y1)^2 Midpoint Formula-  To find the midpoint of the line segment joining the points (x1,y1) and (x2,y2).  Formula: GRAPH OF AN EQUATION Graph of an equation- The set of all points that are solutions of the equation.  To determine the solution points, you need to: o Write the original equation o Substitute the points for x and y o Simplify o If they are equal, it’s a solution. o If they are not equal, it’s not a solution. Point-plotting method-  The basic technique used for sketching the graph of an equation.  The point-plotting method of graphing: o When possible, isolate one of the variables o Construct a table of values showing several solution points o Plot these points in a rectangular coordinate system o Connect the points with a smooth curve or line Intercepts-  Solution points of an equation that have zero as either the x-coordinate or the y-coordinate.  Is possible for a graph to have no intercepts, one intercept, or several intercepts. Finding Intercepts-  To find x-intercepts: o Let y be zero and solve the equation for x 
