Find the determinants of the linear transformations in Exercises 17 through 28.T(v) = x v from the plane V given byxi + 2x2 + 3*3 = 0 to V

L4 - 7 Now You Try It (NYTI): √5 −1 1. Let f(x)= 3x − 1andlt g(x) be a one-to-one function with g (5) = 2. If the point (4,−1) lies on the graph of gd: (a) g (f(0)) −1 (b) f (−1) + g(4) (c) g(f(11)) 2 −1 2. Graph f(x)= x − 4x. Find an interval on which f exists and ﬁnd a formula for f−1 on that interval. 2 Hint: Write f(x)= a(x − h) + k in the standard form. ▯ ▯x▯▯ 3. Use a triangle to simplify csc cos1 . 2
