Question f(x)=xpower2 -4x for x<2 and f(x)=x-4 for xgreater or equal to 2.g(x)=x-3 for x <3 and g(x)=xpower2+2x+2 forx greater or equal to 3.FIND i)f+g ii)f/g
Answer f+g = h
1. for x<2 h(x)=x^2-3x-3
2. for 3≤x (greater or equal) h(x)=x^2+3x-2
3. for 2≤x<3 h(x)=2x-7
Please notice that in (1) I took the smallest value between 2 & 3
& in (2) I took the greatest value between 2 & 3, to determine the
range.
