Evaluate whether or not fish farming would have a negative impact on human health.

fish farming is happening in the ocean environment where excess fish waste is released into the environment. this impacts wild fish that humans consume.
fish farming is happening in the ocean environment where excess fish waste is released into the environment. however, this does not impact wild fish that humans consume.
fish farming is not happening in the ocean environment, so excess fish waste is not released into the ocean.
fish farming is not happening in the ocean environment, so excess fish waste would not impact wild fish that humans consume.

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.
