So I'm working on a piece-wise function. I've simplified them but can't for the life of me remember how to graph it! The book is no help, my simplified piecewise function is 0.30t-20. Can anyone kind of point me in the right direction?

Question

anonymous · Answer

that is not a piecewise function, but in any case the graph will look like a line with slope .3 and y - intercept -20

anonymous · Answer

Well the function was C(t) = 40 + .30(t-200). I was told to simplify then use point-plotting to graph the function. Sorry if I used the wrong terminology =\

anonymous · Answer

Rather, that was one part of the function that was to be used. The first part didn't apply.

anonymous · Answer

yes you are right,that is the same as 
$$C(t)=0.3t - 20$$

anonymous · Answer

so it is a "linear" function, the graph is 
$$y=.3t - 20$$ which is of the form 
$$y=mx+b$$ a line with slope m and y - intercept b

Ah ok. Awesome! Thank you so much.
