Now that you have mapped some of the morphological characters on the evolutionary relationships, you should notice conflicts with regard to these characters defining some clades. What other types of evidence do you think scientists used to support this particular phylogeny, assuming the above phylogeny is correct

In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.                             Hope It Helps Here For Your Help

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
