Only the last two options are true.
The first one is false, because 4.5 is the value of the maximum of f(x), not the point where it is reached.
The second one is false, because g(x) has a maximum of 9, so it is a downward-facing parabola (just like f(x)), so it doesn't have a minimum.
The third one is true, because the maximum value of f(x) is 4.5, and the maximum value of g(x) is 9, which is twice the maximum of f(x)
The last one is false (see point 2).
Answer:
Domain:The set of possible input values (using the “x” variable), which produce an output from a function.

Answer: We know:
the triangle gardern(garden A) and the square garden(garden B) have the same perimeter.
This may sound obv, but it's important: garden A has 1 less side then garden B, which is why it can have longer sides but the same perimeter.
So side A1 + side A2 + side A3 = side B1 + side B2 + side B3 + side B4.
A1 + A2 + A3 = B1 + B2 + B3 + 15(the extra length on the triangle sides)
Since B is a square, B = 15 m by 15 m.
I don't know enough about triangle to put the dementions, but it's an equilateral triangle so the sides are 20 m each. Hope that helps! :)
Using the graph and function concepts, it is found that:
a) The domain is ![[-5,4]](https://tex.z-dn.net/?f=%5B-5%2C4%5D)
, while the range is ![[-2,-5]](https://tex.z-dn.net/?f=%5B-2%2C-5%5D)
b) The function is increasing in ![[0,1]](https://tex.z-dn.net/?f=%5B0%2C1%5D)
and ![[2,3]](https://tex.z-dn.net/?f=%5B2%2C3%5D)
, and decreasing ![[-5,0], [1,2]](https://tex.z-dn.net/?f=%5B-5%2C0%5D%2C%20%5B1%2C2%5D)
, and ![[3,4]](https://tex.z-dn.net/?f=%5B3%2C4%5D)
.
--------------------
- The domain of a function is given by it's input values, that is, the values of x, the horizontal axis on the <em>graph</em>.
- The range of a function is given by it's output values, that is, the values of y, the vertical axis on the <em>graph</em>.
- If the <em>graph </em>is pointing upwards, the function increases.
- If the <em>graph </em>is pointing downwards, the function decreases.
--------------------
Item a:
- On the graph, the x-values are from -5 to 4, thus the domain is:
- The y-values are from -2 to -5, thus, the range is:
--------------------
Item b:
- On the graph, it is pointing upwards on the following intervals, for x-values: From 0 to 1, and from 2 to 3, thus, the function is increasing in and .
- On the other intervals, , and , the function is decreasing.

Answer:
reflective media
Opaque materials such as a printed page or photograph that are scanned by shining light onto them, which is then reflected back to the sensors in order to record the image. Contrast with transparent media
