Oct 4, 2021 · Anaemia can be classified by the mean corpuscular volume (MCV), which is included in a full blood count blood test. The MCV is the average size and volume of a red blood cell. The normal range varies between hospitals as it depends on the equipment in their respective laboratories.
The general form of an absolute value function is f (x)=a|x-h|+k. From this form, we can draw graphs. This article reviews how to draw the graphs of absolute value functions. General form of an absolute value equation: f ( x) = a | x − h | + k. The variable a tells us how far the graph stretches vertically, and whether the graph opens up or ...
- is there any easier steps to explain this type of lessonMaybe I can better explain when you have an absolute value function you want to look at what are in the places of a, h and k. a|x-h|+k Specifically...
- In example problem 1, why isn’t the graph shifted 1 unit to the left instead of to the right?It is shifted to the right because `x-1` would make it `0` when `x=1` because `x=1` `1-1=0` So, we always want the absolute value part of the equat...

- Can Someone solve this hard inequality I've been stuck in for over 30 years solving it. |x+6|>|x-6|𝑥 + 6 = 0 ⇒ 𝑥 = −6 𝑥 − 6 = 0 ⇒ 𝑥 = 6 This means that there are 3 scenarios we need to analyze: 𝑥 < −6 −6 ≤ 𝑥 < 6 𝑥 ≥ 6 – – – Scenario 1 – –...

Nov 16, 2022 · Now, let’s talk a little bit about the subtle difference between the absolute and relative in the definition above. We will have an absolute maximum (or minimum) at x = c x = c provided f (c) f ( c) is the largest (or smallest) value that the function will ever take on the domain that we are working on.
A function, by definition, can only have one output value for any input value. So this is one of the few times your Dad may be incorrect. A circle can be defined by an equation, but the equation is not a function. But a circle can be graphed by two functions on the same graph. y=√ (r²-x²) and y=-√ (r²-x²)

The function has an absolute minimum over [latex][0,2)[/latex], but does not have an absolute maximum over [latex][0,2)[/latex]. These two graphs illustrate why a function over a bounded interval may fail to have an absolute maximum and/or absolute minimum.
Nov 16, 2022 · Definition of a Function. A function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair. Okay, that is a mouth full. Let’s see if we can figure out just what it means.
Where ever input thresholds (or boundaries) require significant changes in output modeling, you will find piece-wise functions. In your day to day life, a piece wise function might be found at the local car wash: $5 for a compact, $7.50 for a midsize sedan, $10 for an SUV, $20 for a Hummer. Or perhaps your local video store: rent a game, $5/per ...
