Examine the list of general trends in human evolution below. Based on your knowledge of our fossil ancestry, put these characteristics in order from oldest to most recent (1= Oldest, 5=Most Recent). For each trend also note which fossil species is first associated with the change (one per species). Anatomical or Cultural characteristics 1) Increase in brain size to an average of over 1,000 cc 2) The oldest production and use of stone tools 3) Adaptations for bipedalism 4) Habitation (living) outside of Africa 5) Clear evidence of symbolic behavior

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.
