Question

I don’t get how to solve it plz help!!

Answer 1

This function is consist of two subfunction with different domains.

f(-1) means x= -1 ≤ 1 and we will use subfunction -x+2 => f(-1)=-(-1)+2= 1=2=3

f(3) means x=3 > 1 and we will use subfunction x∧2-4x+6 =>

f(3)= 3∧2-4*3+6= 9-12+6=3

Good luck!!!
