The information that geologic time scale provide is end date of a geological period and reasons why organisms evolve into different species

Scientists first developed the geologic time scale by studying rock layers and index fossils worldwide. They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth. Geologic time is divided into four large segments called Eons: Hadean, Archean, Proterozoic, and Phanerozoic.

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.
