The function
gives the height
of a ball (in meters) thrown upward from the ground after
seconds. Suppose the ball was instead thrown from the top of a 10-m building. Relate this new height function
to
and then find a formula for
We just saw that the vertical shift is a change to the output, or outside, of the function. We will now look at how changes to input, on the inside of the function, change its graph and meaning. A shift to the input results in a movement of the graph of the function left or right in what is known as a
horizontal shift , shown in
[link] .
For example, if
then
is a new function. Each input is reduced by 2 prior to squaring the function. The result is that the graph is shifted 2 units to the right, because we would need to increase the prior input by 2 units to yield the same output value as given in
Horizontal shift
Given a function
a new function
where
is a constant, is a
horizontal shift of the function
If
is positive, the graph will shift right. If
is negative, the graph will shift left.
Adding a constant to an input
Returning to our building airflow example from
[link] , suppose that in autumn the facilities manager decides that the original venting plan starts too late, and wants to begin the entire venting program 2 hours earlier. Sketch a graph of the new function.
We can set
to be the original program and
to be the revised program.
In the new graph, at each time, the airflow is the same as the original function
was 2 hours later. For example, in the original function
the airflow starts to change at 8 a.m., whereas for the function
the airflow starts to change at 6 a.m. The comparable function values are
See
[link] . Notice also that the vents first opened to
at 10 a.m. under the original plan, while under the new plan the vents reach
at
8 a.m., so
In both cases, we see that, because
starts 2 hours sooner,
That means that the same output values are reached when
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

define infection ,prevention and control

I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
