For the function f defined by f(x)=x^2+2x+3 find f(−x),−f(x) , and −f(−x).also, for the function g defined by g(x)= 55/x +3x find g(−x),−g(x), and −g(−x).!

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
