An equation for a graph which resembles a hump of a camel / pulse in a string?

Question

Sorry if this question isn't valid. I just need to know an equation/function for a graph which resembles something close to

Answer 1

$$\frac{a}{1+b(x-c)^2}+d$$Looks close to your graph.
Try playing around with the constant to get the desired look
a $\rightarrow$represent the maximum value of your function
b$\rightarrow$ represents how steep your function is
c$\rightarrow$represents the x co-ordinate of your peak
d$\rightarrow$represents the minima of the function
$$ae^{-b(x-c)^2}+d$$Also looks close to your graph.Constants carry the same meaning
