Question

Evaluate expressions of the graph:

Answer 1

• 1) - 3; 2) 3; 3) - 1; 4) 5; 5) 6

---------------------

Evaluate expressions using respective points on graphs :

• 1) (f · g)(2) = f(g(2)) = f(0) = - 3
• 2) (g · f)(2) = g(f(2)) = g(5) = 3
• 3) (g · g)(5) = g(g(5)) = g(3) = - 1
• 4) (f · f)(5) = f(f(5)) = f(2) = 5
• 5) (f · g · f)(4) = f(g(f(4))) = f(g(5)) = f(3) = 6
