Graphs of piecewise functions. ?Write a definition of the functions whose graphs are given

The graph is composed by two linear functions, one goes from (0,3) and the other from (3,8) , we have to determine their equations. y2y1 m = x2x1 equation for the slope of a linear function given 2 points as data) where: (x1,y1)= (0,1) and (x2,y2)=(1,2), substituting: 21 m = 10= 1 Substituting the value of the slope and one of the...
