A- Graph B shows exponential growth of a population. Graph B is a type of exponential equation where y=a(b)^x
"a" is the initial value that intercepts the y-axis in the above equation.
"b" is the value that every value thereafter is growing (multiplying by). Note, if "b" is 1- your value is not growing (since it is staying at it's original 100%). If "b" is, for example 1.5 your value is growing by 50% each time (1 gives you your original 100%, and the .5 gives you an additional 50% on top of that).
"x" is your input, and here it is the exponent because you are multiplying "b" to the power of your input for each value.
La característica en común es que esos países subdesarrollados concentran la mayor cantidad de empleos en el sector terciario o de servicios. Espero que te ayude!
