Find the x and y-intercepts: f(x) = -log(x+2) - 3?

Can you walk me through how to find the x and y-intercepts for a logarithm?

    to find the x and y intercept, we first put x = 0

    then: f(x) = f(0) = -log(0+2) -3 = -log2-3;

    now we want f(x) = 0 ---> -log(x+2)-3 = 0

    ---> log(x+2) = -3

    ---> x+2 = e^-3

    --->x = e^-3 -2

    ...hope u got it:)
