On e2 (cf. 3.1-4) let the operator T: e2 e2 be defined by Tx = (gl + ig2, gl - ig2), where x = (gl, g2)' Find T*. Show that we have T*T= TT* = 2I. Find TI and T2 as defined in Prob. 4

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
