What is the effect on the graph of the parent function f(x) = x when f(x) is replaced with f(x) - 4? a) shifts the line 4 units up b) shifts the line 4 units down c) increases the slope of the line by a factor of 4 d) decreases the slope of the line by a factor of 4

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
