Based on the graphs of f (x) and g(x), what must the domain of (f ⋅ g)(x) be?
bekas [8.4K]

Using the concept of domain, the domain of (f.g)(x) is given by:

{x ∈ ℝ | x ≠ 3}

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

  • The domain of a function is given by all possible input values, that is, <u>on a graph, all values that the x-axis assumes.</u>
  • In the graph, <u>function f assumes all real values.</u>
  • Function g is not defined for x = 3, thus, it's domain is all real values except 3.
  • Thus, the multiplication, as fg(x) = f(x) \times g(x), will also not be defined at x = 3, and the domain of the multiplication is:

{x ∈ ℝ | x ≠ 3}

vodomira [7]

Answer:

80 hours   for 2 workers  to build 8 cars

Step-by-step explanation:

2 cars / 8w *5 hr  =   2 cars / 40 hrs    1 car takes 20 hrs

8 cars * 20 hours = 160 hours required

 two workers split this time    160/2  = 80 hours
