<h3>Answer: Choice D</h3>
Domain = [-3, infinity)
==================================================
Work Shown:
In step 2, we replaced every x with g(x)
In step 3, we plugged in g(x) = sqrt(x+3)
The domain of g(x) is [-3, infinity), so this is the domain of as well since the composite function depends entirely on g(x). Put another way: the input of f(x) depends on the output of g(x), so that's why the domains match up.
The distance between points (a) and (b) is the number of units between the points.
<u>Formula for halfway two</u>
Assume the lesser point is point (a)
To locate the halfway between points (a) and (b)
- Calculate the absolute difference between points (a) and (b) i.e. |a - b|
- Divide the difference into halves
- Add the value of one half to point (a).
The above steps is represented as:
Using the above formula, the halfway point between 5 and 11 would be 8
The formula can be used to calculate the distance between negative points, and absolute values are used to determine the number of units between the points
<u>Real world circumstance</u>
The formula can be used to calculate the halfway distance between two points on a track
<u>Fractional distance</u>
To determine the fractional distance, we simply replace the 1/2 in the original formula with the appropriate fraction.
Take for instance, three-fourths from (a) to (b) would be:
