find h'(2) given that f(2) = -3, g(2) = 4, f'(2)= -2 and g'(2)= 7.

A. h(x) = 5f(x) - 4g(x)

B. h(x) = f(x)g(x)

C. h(x) = f(x)/g(x)

D. h(x) = g(x)/ 1+ f(x)

  • calculus -

    simply chart it out.
    f(x) g(x) f'(x) g'(x)
    2| -3 4 -2 7

    then plug them into the equations.
    A. (5)-3 - 4(4)
    -15 - 16 = -31

    B. (-3)4 = -12

    C. -3/4

    D. 4/1-3
    = 4/-2 = -2

  • calculus -

    well the chart didn show up right but when x = 2 then
    f(x) = -3
    g(x) = 4
    f'(x) = -2
    g'(x) = 7

    then plug them into the equations.
    A. (5)-3 - 4(4)
    -15 - 16 = -31

    B. (-3)4 = -12

    C. -3/4

    D. 4/1-3
    = 4/-2 = -2
