Biodiversity contributes to the sustainability of ecosystems because... *
1 point
It creates competition between species of organisms, which is healthy for survival.
It creates multiple sources of food and energy for organisms in the environment, so they are less reliant on individual populations.
It increases the abiotic factors in an ecosystem, therefore providing a better climate for organisms.

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.
