Hello, i had this exercice but i donèt understand what: f:R→R means? Does it mean fonction on 1st degre, like for exemple f(x)=3x+b or not Thank in advance

If i have this matrix in maple, what does it mean the last row (0 0 0 0 1) and what is 1? Is it like 2a+5b-6c+2d+6e=1. View 6573_problem.mw on MapleNet or

I had a new homework in maple but there is two questions that i have a hard time figuring them out. If somewone could help me it would be nice. 1. It says that E=L{v1,v2,v3,v4} (all vectors) where v1= (-5,3,2,0,1), v2=(0,-1,1,3,0), v3=(3,1,0,0,2) and v4=(1,4,4,2,0). Discribe E, which is a subset of R5 (and the teacher would like a description like this exemple: E={(x,y) ∈R2 ∣ 2x-3y=2} 2. A matrix: A := Matrix(5, 5, {(1, 1) = 1, (1, 2) = 0, (1, 3) = 0, (1, 4) = 0, (1, 5) = 0, (2, 1) = 0, (2, 2) = 4, (2, 3) = 0, (2, 4) = 0, (2, 5) = 0, (3, 1) = 0, (3, 2) = 0, (3, 3) = 52, (3, 4) = 0, (3, 5) = 0, (4, 1) = 0, (4, 2) = 0, (4, 3) = 0, (4, 4) = 7, (4, 5) = 0, (5, 1) = 0, (5, 2) = 0, (5, 3) = 0, (5, 4) = 0, (5, 5) = 3})
