Letf: R2
→ R be defined by f((x, y)) = 7x + 7y + 1. Isf a linear transformation?
a. f((x₁, y₁) + (x₂, y₂)) =
b. f(c(x, y)) =
f((x₁, y₁)) + f((x2, y₂)) =
+
Does f((x₁, y1) + (x₂, y₂)) = f((x₁, y₁)) + f((x2, y2)) for all (x₁, y₁), (x2, y2) ER2? choose
. (Enter x₁ as x1, etc.)
c(f((x, y))) =
Does f(c(x, y)) = c(f((x, y))) for all c ER and all (x, y) = R²? choose
c. Is f a linear transformation? choose
