Question

Filling in the blanks for part a, b and c

For part a and b, where it says "choose" the options are
1) yes they are equal
2) no they are not equal

For part c, where it says "choose" the options are
1) f is a linear transformation
2) f is not a linear transformation

Let f : R? → R be defined by f((x, y))
9x + 6y. Is fa linear transformation?
a. f((x1,Y1) + (x2, Y2))
(Enter a1 as x1, etc.)
f((T1, 41)) + f(x2, Y2)) =
+
Does f({r1,Y1) + (x2, Y2)) = f((x1, Y1)) + f({x2, Y2)) for all (x1, Y1), (r2, Y2) E R?? choose
b. f(c(x, y)) =
c(f({x, y))) =
Does f(c(x, y)) = c(f({x, y))) for all c e R and all (x, y) E R?? choose
c. Is fa linear transformation? choose
