The function which represents the reflection of provided function across the x-axis is,
<h3>What is reflection of function?</h3>
The reflection of a function is flipping the original function with respect to a reference line.
The following steps used to for reflecting a the function-
- Select the function which has to be reflected.
- Select a baseline or reference line over which the function has to be reflected.
- Mark the corners of the function at the equidistant from the reference line as the original function has, but in the opposite direction.
- The reflected function is now is facing the opposite direction.
The function given in the problem is,
The function has the positive sign. Therefore, this function is located in the first quadrant.Now this function is reflected across the x-axis. This will lead this function in the fourth quadrant, with negative sign.
Therefore, the function become,
Hence, the function which represents the reflection of provided function across the x-axis is,

Answer:
7.5 weeks
Step-by-step explanation:
If you want to find out how long it take for the plant to reach a foot you set up the equation like so:
12=1.2w+3
and solve from there.
12=1.2w+3 Subrtact 3 from both sides
9=1.2w Divide by 1.2 to isolate w
7.5=w Answer is 7.5 weeks
Based on the function shown on the graph, the statement that is true is: <em>D. The candle started at 9 mm and shrinks 5 mm every 4 minutes</em>.
<h3>What is a Function?</h3>
A function is a relationship between input and output values.
On a graph, the average rate of change represents the unit rate, while the point where the line intercepts the y-axis is the initial value or starting value.
Therefore:
The starting value = 9 mm (the candle length when it started burning).
In conclusion, based on the function shown on the graph, the statement that is true is: <em>D. The candle started at 9 mm and shrinks 5 mm every 4 minutes</em>.
