What is the advantage of using technology such as NASA's Global Precipitation Measurement mission for predicting weather? It uses several radars instead of rain gauges.
It collects precipitation data from both land and oceans.
It studies all types of precipitation in technically advanced nations.
It uses a vast network of rain gauges installed over difficult types of terrain.

a compound light microscope is used to magnify objects in steps.

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.

to this one it would be receptive field
