Where is the graph?
Here's the table of values since i don't know how to insert the graph here
I hope you'll understand this.
table of values for the parabola ^^^
so apparently from a "u"" parabola the curve like it jumps or flip to the other side
table of values when it flips to the other side ^^^ (the curve here goes to (0,6))the third row which is (-2,1) is a hole
I hope you'll understand this.
| x | f(x) |
| -5 | -5 |
| -2 | 4 |
| -1 | 5 |
| 0 | 1 |
| 1 | -2 |
| 3 | 3 |
| 4 | 2 |
| 5 | 6 |

Graphs of functions. Find (f+g)(0)
The process is like this f(0) + g(0)
And, the answer is 7
How do you find it through a graph with table of values provided?
Here's the table of values:
From this:
To this (from the graph that is shown but not here because I don't know how to insert it + I don't have phone)
point (3, -3)
point (-2, 1) with hole
point (-2, 2)
There are space between the hole point (-2, 1) and point (-2, 2)
The process is like this f(0) + g(0)
And, the answer is 7

Is that g(x)?

Please quote exactly what the problem says!
Since nothing you have shown us says what g is, I'm guessing that they gave you a table for f, and a graph for g.
You need to find f(0) + g(0). The table shows what f(0) is. From the graph, you have to find g(0). You have not described the graph in enough detail to be sure, but I wonder if the graph is a straight line passing through (3,-3) and (-2,1), but with a hole at (-2,1) and an extra point at (-2,2) -- that is, g(3) = -3, and g(-2) = 2. If so, then it should be easy to read off g(0).
So, what are f(0) and g(0)? Then, just add them to get the answer. Unfortunately, I don't find the answer to be 7 if my guesses are right, so I must have something wrong!
