Suppose a non-homogeneous system of six linear equations in eight unknowns has a solution, with two free variables. Is it possible to change some of the constants on the equations’ right sides to make the new system inconsistent? Explain.

Describe the end behavior of the function below. f(x)=(2/3)^x-2 a. as x increases, f(x) approaches infinity. b. as x decreases, f(x) approaches 2. c. as x increases, f(x) approaches -2. d. as x decreases, f(x) approaches negative infinity.
