For the following exercises, graph the transformation of f(x) = 2x. Give the horizontal asymptote, the domain, and the range.
h(x) = 2x + 3
Consider the graph of the function;
h(x) = 2x + 3
The horizontal asymptote of the function is determined as follows:
Check horizontal asymptote for x = ±∞;
h(∞) = 2∞ + 3
= 0 + 3
= 3
Therefore, the horizontal asymptote is h(x) = 3.
Domain of the graph is set of all real numbers, that is (-∞, ∞).
Range is set of all real numbers greater than 3.
The graph of the function y = 2x + 3 is shown below;
