Question

obtenha nesse caso a lei da função cujo gráfico mostrado a seguir

Answer 1

Y=AX+B                       y=ax+b 
11/3=a+b                     11/3=4a+bmontando um sistema
a+b=11/3               (-1)     -a-b=-11/3                   a+b=11/3
                                                                             0 +b=11/3
4a+b=11/3                      4a+b= 11/3                      b=11/3
                                     
                                       3a=0                                        a=0/3                                        a=0A lei de formação é y=11/3
