anybody Help Me with Graphing functions?

Question?

OpenStudy (anonymous):

Nothing specific just In general..

OpenStudy (the_fizicx99):

Well they could either be linear or exponential, a linear function will always increase a constant rate. An exponential function will grow at a much faster rate, just remember that if its below 1 it'll be a decay. If its above 0.99 it'll be a growth, -- I'm talking about the rate. Usually you'll have like: f(x) = mx + b where M is the slope and b is the y intercept. So you would plot it at (0,b) and do Rise/Run. Btw, f(x) is another way of saying y.

OpenStudy (the_fizicx99):

It's read f of x or function of x, pretty much meaning y

OpenStudy (anonymous):

Oh ok i see what you're explaining now so you take f of x and plug it into the equation as a seperate number as lets say A -2 Then do the math as F(x)=mx=b?

OpenStudy (anonymous):

But You also need a slope right?

OpenStudy (the_fizicx99):

Well, suppose your given f(x) = 2x + 3 So you plot the y intercept, and you plug in any value you want for x and you'll get an output. So suppose I wanted to plug in 5 for x, f(5) = 2(5) + 3, 2*5 = 10 10 + 3 = 13 f(5) = 13 A function can be used for so many things, you'll always get an output :p

|dw:1391981784666:dw| It looks something like this

OpenStudy (anonymous):

Oh Much enthusiasm aha. Thank you I appreciate it, It makes more sense now that i think about it.

OpenStudy (the_fizicx99):

yw :p

OpenStudy (anonymous):

Will it always come out to be a line that connects?

OpenStudy (anonymous):

Or will it depend on tthe problem

OpenStudy (the_fizicx99):

Depends
