    Answer:

    (0,-1)

    Step-by-step explanation:

    The y-intercept always occurs when x=0. To find the y-value of the y-intercept, substitute x=0 into your equation:

    Given f(x)=-4.2^x, when x=0:

    f(x)=-4.2^0,\\f(x)=-(1)=-1

    • Recall that n^0=1 for n\in \mathbb{R}

    Therefore, the y-intercept of this function is (0, -1).
