So I'm saying this, "Notice that the graph of y increases/increasing without bound when x approaches negative infinity."
I suspect that both would work in this case. Is that true?

Notice the graph of y increasing without bound when x approaches negative infinity.
........btw, if you have an exponential function f(x) = exp (kx) where k=constant> 0, doesn't the function go to 0 at negative infinity and to positive infinity when x approaches positive infinity?
And about your remark "if you have an exponential function f(x) = exp (kx) where k=constant> 0, doesn't the function go to 0 at negative infinity and to positive infinity when x approaches positive infinity", as x approaches negative infinity, I'm afraid the function only tends to zero but not actually reaching the zero value, this graph may help[:)]: http://algebra.freehomeworkmathhelp.com/Relations_and_Functions/Exponential_Functions/exponential...
Anyway, thanks for your help.
You need 'increases', as shown.
It's not the graph of y that increases, by the way. It's y (as a function of x) that increases.The graph itself is a static picture of the function, and it doesn't do anything. It doesn't increase or decrease. It just sits there on the paper for us to look at.
"animated" explanation!!! The penny finally dropped.
P.S. Which of the following sentence is correct in an attempt to express the idea of I finally gained the complete understanding to what I first seek?
Is it "The penny is finally dropped", "The penny has dropped" or "The penny finally dropped" that is correct?
People are waiting to help.
