in qs like these why is it when we have equations like “f(x)=16 if x<3” the range is put in a square bracket although the inequality sign isn’t <= or =>??
i thought u only put square brackets when it’s <= or =>
for example “f(x)=5x of x<2” and “f(x)=x^21 for x<0” uses normal brackets since they use < or > and not <= or =>. this makes sense as to why they use normal brackets but why are horizontal lines exceptions???
