Describe the graphs of the functions f(x) = 2x – 3 and g(x) = –2x – 3. Compare and contrast the domain and range of f(x) and g(x).

Answer 1

both straight lines, first has a slope of 2 and y-intercept of -3
the 2nd has a slope of -2 and also a y-intercept of -3

both have domains and ranges of x ∈ R
