Which of the following best explains why clear-cutting forests is more destructive than selectively cutting down trees in forests?
a. clear-cutting eliminates all trees leaving none behind to maintain soil fertility or house native animals
b. clear-cutting places the land at greater risk for wildfires.
c. clear-cutting makes land more attractive for human development.
d. clear-cutting causes less soil erosion than selective cutting.

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.
