hi all members, I cannot answer this question can anyone please help me and teach me by steps? Thanks!
An equation of the form Y=2[e^(x/2c)+e^((-x)/2c)] where c is a constant. So, for positive, how C affects the graph and equation?
Then your function is $\displaystyle f\left(\frac{x}{c}\right)$ and so the effect of positive $\displaystyle c$ is to dilate in the horizontal direction by a factor of $\displaystyle c$.
