F(x)=(x-8)/7
<span>g(x) = 7x + 8
</span>g(f(x))-------------- > 7*((x-8)/7)+8----------- >x-8+8=x
the answer is x
Add every thing and u. Get 10.10 7x2 then 14. Then add 10 so u basically just in total get 14.10
Answer:
i) D: All real numbers
ii) R: 
iii) Y-int: b=2
Step-by-step explanation:
i) The given absolute value function is

The domain is all values of x that makes the function defined.
The absolute value function is defined for all values of x.
The domain is all real numbers.
ii) The given function is 
The function has vertex
.
The function is reflected in the x-axis.
This means the vertex is the maximum point on the graph of the function.
The maximum y-value is 5.
The range is therefore
or ![(-\infty,5]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C5%5D)
iii) To find the y-intercept, put
into the function.




The y-intercept is (0,2) or 
See attachment for graph.

1) Triangles are the only polygons with three sides.
2) The polygon has three sides.
3) Thus, triangles are polygons.
