- Linear transformations can be used in computer graphics to modify certain shapes. Consider the linear transformation T: R2 R2 below such that T(A) = B, where A represents the square and B the parallelogram below. 1 1 B 1 1 y. y 1 1 2 X Tarrow_forwardDetermine whether the function is a linear transformation.

The manufacturing cost includes labor, materials, and overhead (facilities, etc.). The company's costs (in dollars) per unit for each type are summarized in the following table. js J8+ 57 73 81 Labor Materials 93 101 113 Overhead 29 34 38 Suppose T is the linear transformation that takes as input a vector of unit counts for jg's, jg+'s, and jo's respectively, and produces for output a vector of total labor, material, and overhead, respectively. Find a formula for T. (A graphing calculator is recommended.) T(x) = ول Determine 7-1, and use it to find the production level for each type of phone that will result in the given costs.
