Lessons

multiplying functions: (fg)(x)=f(x)g(x)(fg)(x) = f(x)\cdot g(x)
  • 1.
    Determine the Product of Two Functions Algebraically
    If f(x)=2xf(x)= 2-\sqrt{x}
    and
    g(x)=7x3 g(x)=7\sqrt{x}-3
    Determine:
    a)
    (fg)(x) (fg)(x)

    b)
    (fg)(25) (fg)(25)
    evaluate in two different ways


  • 2.
    Determine the Product of Two Functions Graphically
    Given the graph of functions f(x) f(x)
    and g(x)g(x),
    sketch the product of these two functions(fg)(x)(fg)(x)
