Assuming the light is on and the oculars are in place what are the next 2 steps

If the light is on and the oculars are in place, then we should adjust the lens so that we could get the clear image. The second step is put the eye on the eyepiece view the sample which is placed under oculars.

Explanation:

Microscope is a common device which is used in the laboratory. This can be used in physics, chemistry and biology lab. But it is more common in biology lab.

It is so because the microorganisms are very common and they cannot be seen by naked eyes so the scientist use microscope to view them. To have a proper observation of microorganism the light should be perfect and the ocular should be adjusted perfectly.

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.
