What is the y intercept, function, domain and range, and horizontal asymptote of y=3^x

Answer: y-intercept is = (0,-2), the horizontal asymptote is y=4, Domain is - ∞ < x < - 2 and - 2 < x < ∞, Range is - ∞ < y < 4 and 4 < y < ∞

Step-by-step explanation: Vertical asymptote can be found by setting the denominator equal to 0 and solving for x :, Horizontal asymptote can be found by evaluating yas x→±∞,
