The chess club started with a membership of only 4 students, but the membership grew at a rate of 2.56% each week. The number of students is modeled by f(x) = 4(1.0256)x.

A: Create a question you could ask that could be answered only by graphing or using a logarithm.

Respuesta :

The question that could be answered by using a logarithm is explained below

How to explain the logarithm?

The question is: Let your dependent variable in the function be y. Write the function that models the independent variable in terms of y, using logarithms.

The question is asking you to solve y = f(x)

You already did this using a constant for y. Do the same thing with y instead of the constant.

y = 4(1.0256^x)

y/4 = 1.0256^x . . . . . . . divide by 4

log(y/4) = x·log(1.0256) . . . . . take logs

log(y/4)/log(1.0256) = x . . . . . divide by the coefficient of x

Now, you have a model for x in terms of y, which is what the question is asking for.

x = log(y/4)/log(1.0256)

When y=12, this is .x = log(12/4)/log(1.0256) ≈ 43.46 weeks
