Step 1
Using the formula given, we can see that f(x) = 2x, which is clearly a vector in R2. Therefore, f is well-defined. Next, we need to check if f is linear. To do this, we need to verify two properties: Show more…

(25 points) For each of the following: determine whether the given function is a linear transformation. If it is a linear transformation, prove it by showing that it satisfies the conditions of a linear transformation. If it is not a linear transformation, give a specific example that shows that it fails to meet part of the definition. (a) f: R→R given by f(x) = 4 + ∑x (25 points) Does there exist a matrix transformation T: R→R' such that T([8,3]) = [H] and T([i]) = [83]?
