What is currently being done by organizations around the world to fix the effects of recycling?

So much is being done across the country to help spruce up our environment. Recycling has picked up over the past several decades and continues to build traction in every state thanks to recycling initiatives, legislation, and the efforts of nonprofit organizations. According to the EPA, the national recycling rate has increased from about 10% in 1985 to about 35% in 2012. It has steadily increased year after year due to advancements in recycling technology and the realization that recycling has a major economic impact. Oh…not to mention the huge environmental benefit! A good way to quickly dispose of heavy or bulky waste in a way that is environmentally responsible is through the use of a dumpster. Depending on the type of waste processing facilities near you, you may be able to save money (and the environment) by "clean" loading your dumpster with only one type of debris, such as asphalt roofing shingles, concrete, or drywall.

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.
