Pls help, this is science btw. Invasive species are organisms that aren't native to an ecosystem. Humans introduce invasive species into an area on purpose or by accident. At times, organisms move into an area because of loss of habitat or other environmental changes. Do you think invasive species affect the native species in an ecosystem? Why are why not?

check for the pregnancy rating of drug. if its class c or d see if other alternatives

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .

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.
