Объяснение:

1) y(0)=4*0-3=-3;

y(-3)=4*(-3)-3=-12-3=-15;

y(9)=4*9-3=33;

y(1,5)=4*1,5-3=3;

2) y(0)=5+2*0=5;

y(-3)=5+2*(-3)=5-6=-1;

y(9)=5+2*9=5+18=23;

y(1,5)=5+2*1,5=5+3=8;

3) y(0)=7- $\frac{2}{3}$*0=7;

y(-3)=7- $\frac{2}{3}$*(-3)=7+2=9;

y(9)=7- $\frac{2}{3}$*9=7-6=1;

y(1,5)=7- $\frac{2}{3}$*1,5=7-1=6;

4) y(0)= $\frac{5}{6}$ *0+2 = 2;

y(-3)= $\frac{5}{6}$ *(-3)+2 = -2,5+2= -0,5;

y(9)= $\frac{5}{6}$ *9+2 = 7,5+2=9,5;

y(1,5)= $\frac{5}{6}$ *1,5+2 = 1,25+2=3,25/
