Give a geometrical interpretation of a linear equation in three unknowns. Give a geometrical description of the possible solution sets for a 3 3 linear system.

L24 - 9 Now You Try It (NYTI): 2/3 1. Let f(x)= x − 2. Show that f(−1) = f(1) but there is no value of c in (−1,1) so that f (c) = 0. Why does that not contradict Rolle’s Theorem 2. If f(2) = −2a d f...
