    Answer:

    The range of the function is (-∞,3)

    B is correct.

    Step-by-step explanation:

    Given: f(x)=-2(6)^x+3

    It is an exponential function which coefficient is negative.

    Exponential function: f(x)=ab^x+c

    If a>0 then range (c,∞)

    If a<0 then range (-∞,c)

    -2(6)^x+3\rightarrow ab^x+c

    a=-2

    c=3

    Range: (-∞,3)

    Hence, The range of the function is (-∞,3)
