If f(x)=x^2-2 and g(x)=1/(3x) (x does not equal 0), find (fxg)(-2)

  • Math - ,

    Given:
    f(x)=x²-2
    g(x)=1/(3x)
    I assume you are working with composite functions, and you are looking for
    (f∘g)(x)
    =f(g(x))
    =f(1/(3x))
    =(1/3x)²-2
    =1/(9x²)-2
    (f∘g)(2)
    =1/(9*2²)-2
    =1/(9*2²)-2
    =1/36-2
    =-71/36
