What are the domain and range of f(x) = (1/6)x + 2?
Black_prince [1.1K]
F(x)=x/6+2

There is no restriction upon the values of x, or the values of y.

So the domain and range are both the set of all real numbers.

x=(-oo, +oo) and y=(-oo, +oo)

This can be further seen by the fact that this is a line with a slope of 1/6.  So there is no restriction upon x as all values of x produce real values of y.  And y approaches -oo as x approaches -oo and y approaches +oo as x approaches +oo.

:<br> Find the area of the figure and choose the appropriate result.
Neporo4naja [7]

Answer:

41.7m²

Step-by-step explanation:

As we can see, the area of this shape is simply the sum of 3 rectangles

Rectangle A has an area of 6 times 4 or 24m²

Rectangle B has an area of (3.8-2) times 3.5 or 1.8 times 3.5 or 6.3m²

Rectangle C has an area of 3 times 3.8 or 11.4m²

Adding that up gives 41.7m²
