What is the domain, range, end behavior, asymptote, decreasing, increasing, positive and negative of the exponential function?

Question

What is the domain, range, end behavior, asymptote, decreasing, increasing, positive and negative  of the exponential  function g(x)=-2^{x + 4}

Answer 1

y = - 2^(x+4) has domain x = any real number, range y all non positive numbers

asymptote is y = 0, it's everywhere decreasing

end behavior is approaching negative infinity as x approaches positive infinity

and vice versa
