f and g are functions defined as f(x)=5x+6/2x−2 and g(x)=4x/3x−2. What is the value of (f∘g)(4)?

Note: f∘g denotes the composition of the 2 functions.

  • maths -

    f∘g(x) = f( (g(x) )

    I will assume you meant:
    g(x) = 4x/(3x-2) and f(x) = (5x+6)/(2x-2)
    those brackets are essential

    g(4) = 16/10 = 1.6
    f( g(4))
    = f(1.6)
    = 14/1.2 = 140/12= 35/3
