Best ResponseYou've already chosen the best response.0look at the graph what is \(f(2)\)?

Best ResponseYou've already chosen the best response.0\[(f+g)(a)=f(a)+g(a)\]\[(fg)(a)=f(a)g(a)\]\[(fg)(a)=f(a) \times g(a)\]\[(\frac{f}{g})(a)=\frac{f(a)}{g(a)} \space ; \space g(a)\neq 0\] Use these formulae and find the values from the graph

Best ResponseYou've already chosen the best response.0so to find for your first part \[(f+g)(2)=f(2)+g(2)\] you do it like that and the value of f(2) and g(2) may be obtained from the graph

Best ResponseYou've already chosen the best response.0yep! what are the y values for these points

Best ResponseYou've already chosen the best response.0Think of your f(x) as yvalues for the blue curve and g(x) as the yvalues for the pink straight line so to find f(2), we find the corresponding y value for the x value 2 on the blue curve and to find g(2), we find the corresponding y value for the x value 2 on the pink straight line

Best ResponseYou've already chosen the best response.0Hmm..okay..Now what? :/ still kind of confused

Best ResponseYou've already chosen the best response.0you've found your \[f(2)=4\]\[g(2)=0\] Because 2,4 is a point lying on the blue curve and 2,0 is a point lying on the pink straight line

Best ResponseYou've already chosen the best response.0basically u look at the x value, look for what value of y for that x we have a point lying on the curve and the line

Best ResponseYou've already chosen the best response.0Ok do I add or subtract the numbers now? I think I remember learning that.

Best ResponseYou've already chosen the best response.0\[(f+g)(2)=f(2)+g(2)\] add them up :)

Best ResponseYou've already chosen the best response.0Sorry got confused there. Now I get it...Lol. Ok for the next one, f(1)= 1 right?

Best ResponseYou've already chosen the best response.0and g(1)=3...so answer would be 4 also?

Best ResponseYou've already chosen the best response.0No! this time you are subtracting! \[(fg)(1)=f(1)g(1)\]

Best ResponseYou've already chosen the best response.0Ok I see that now lol So it would be 2

Best ResponseYou've already chosen the best response.0An interesting thing to note here, if by chance your g(1) was 0, you would say that that your (f/g)(1) is not defined, as you can't divide by 0 \[(\frac{f}{g})(1)=\frac{f(1)}{g(1)}=\frac{f(1)}{0}\]
