Answer:
![f(1)=-4](https://tex.z-dn.net/?f=f%281%29%3D-4)
Step-by-step explanation:
For finding out
, we have to find the value of y coordinate of the point where its x coordinate is 1.
From the given graph, the point
lies on the graph and has x coordinate as 1.
Drawing a vertical line x=1, it meets the graph at ![(1,-4)](https://tex.z-dn.net/?f=%281%2C-4%29)
Therefore, ![f(1)=-4](https://tex.z-dn.net/?f=f%281%29%3D-4)
Answer:
1.) 19
2.) 5
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
The domain and range are correct.
The relation is a function because no x value is used more than once.
Answer:
see below
Step-by-step explanation:
it will be easier to do calculations later if you simplify first
in this case you did the best and shortest way
you could rewrite
(8-4√2) /2 + ( 6+4√2)/ 2 as
4-2
+ 3 + 2
and then 7 + 4![\sqrt2](https://tex.z-dn.net/?f=%5Csqrt2)
