A number of different species of birds that eat the same insects are placed in a habitat. It was expected that one species of bird would outcompete the others for the food source, causing the all of the other species to become extinct. Surprisingly all species experienced success, increasing their population size over time. What do these data show about the interactions between the species of birds in this situation

it marks things for degradation via the proteasome. it alters there celluar location.

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.
