What are the domain, range, and asymptote of h(x) = (1.4)x + 5?

Interpreting the function as the exponential function h(x) = (1.4)^x + 5, every real x is allowed, so the domain is all real numbers. Since (1.4)^x is always positive, h(x) is always greater than 5. As x decreases, (1.4)^x approaches 0, so the horizontal asymptote is y = 5; this matches choice A.
