Q3(0 points)(a)Consider f(z)=1+3x x3()Find T3,a(c)fora∈R(il)Expand and simplify T3,a(r)as much as possible.How does the simplified T3,a(c)relate to f(x)?(b)Letmom=VL-v7c2where mo and c are constants and v is the independent variable.If u c(that is,v is much smaller than c),showthat K=mc2-moc2 approximates to Kmov2.[Hint:letxv/c and consider what v cimplies for therange of values of x.]
