Question

ex4!va rog frumos!este urgent!
la a)4 ; b)3 ; c)3 ; d)3.

Answer 1

Răspuns:

Ea) (fog)(-3,2) = f(g(-3,2)) = f([-3,2]) = f(-4) = |-4| = 4

b) (gof)(-3,2) = g(f(-3,2)) = g(|-3,2|) = g(3,2) = [3,2] = 3

c) (fog)(3,2) = f(g(3,2)) = f([3,2]) = f(3) = |3| = 3

d) (gof)(3,2) = g(f(3,2)) = g(|3,2|) = g(3) = [3] = 3
