Question

@satellite73 This one has a graph. I am not good at reading graphs. Screenshot is below.

Answer 1

@satellite73

Answer 2

zelda if you know as well all help is welcome!

Answer 3

\[f(x) = x^2\] and \[g(x) = -x+1\]

Answer 4

Can you do it now?

Answer 5

let me give it a shot. (f+g)(-2)=(-2^2)+(2+1)

Answer 6

so therefore 4+3

so 7

Answer 7

@Zelda how did you get those equations from the graph? im curious as i have issues reading those often. :)

Answer 8

Well, if you look at the f(x) equation. You can see that for x = 1. y = 1. For x = 2, y = 4, and so on.

Answer 9

For g(x) it's a negative slope, and it goes down and right one square each time. So rise/run = -1/1 = -1 = -1*x = -x, and it is one point above the origin, hence + 1

Answer 10

ah i see thanks! That helps a ton! i can get it from here!

Answer 11

Right on. :)
