- 7. Determine if the following transformations are linear. Justify your answer. (a) T: R² → R³ such that T(x₁, x2) = (2x₁ + 3, 3x₁ − 2x2 + 5,4x2) (b) T: R³ R³ such that the transformation T takes a vector in R³ and stretches it by a factor of 4.arrow_forwardplease solve it on paperarrow_forwardLet f (z) = (az + b)/(cz + d) and ad – bc + 0. If this transformation maps zo Wo, Z1 → W1 and z2 → W2 (in other words, if three points and their images under this bi-linear transformation is specified) show that f (z) can be found uniquely. (Hint: Write W; = (az; + b)/(cz; + d), i = 0,1,2 and convert this three equation to a linear equation system of three equations, whose unknowns b c d are and the right hand side includes terms having z0, Z1, Z2, Wo, W1, W2.
