Question: (1 point) Let f : R2 - R be defined by f((x, y)) = -4x - 6y + 8. Is f a linear transformation? a.

(1 point) Let f : R2 - R be defined by f((x, y)) = -4x - 6y + 8. Is f a linear transformation? a. f((x1, y1 ) + (x2, y2)) = 4(x1+x2,y1+y2) (Enter x1 as x1, etc.) f ((x1, y1)) + f((x2, >2)) = 4(x1+x2) + 4(y1+y2) Does f((x1, y1 ) + (x2, y2)) = f((x1, y1)) + f((x2, y2)) for all (x1, y1), (x2, 12) ER? Yes, they are equal b. f(c(x, y)) = C(-4x-6y) c(f ( (x, y))) = Does f(c(x, y)) = c(f((x, y))) for all c E R and all (x, y) E R? Yes, they are equal c. Is f a linear transformation? f is a linear transformation
