Question

Graph and find the x-intercept, y-intercept, domain, range, and horizontal asymptote of the function y = 4x

Answer 1

The function $y=4x$ is a line. As such, its domain and range is the whole real number set $\mathbb{R}$, and it has no horizontal nor vertical asymptotes.

Moreover, there's no constant term, so it's x and y intercept is the origin (0,0).
