Question

Multiple Choice: If Ken wanted to create a function that modeled an exponential function with base of 11 and what exponents were needed to reach specific values, how would he set up his function? (1 point)

[A] f(x) = 11^x
[B] f(x) = x^11
[C] f(x) = log_11(x)
[D] f(x) = log_x(11)

Answer 1

I donI was thinking A

Answer 2

maybe C? because then I could just give the function a number and it would return an exponent for 11^

Answer 3

the wording on this question is terrible. What should we expect the function to return? A specific value, or an exponent?

Answer 4

the form of an exponential function would be 5^x

Answer 5

my choice would be A

Answer 6

but if it " modeled an exponential function" does that mean that it is not actually an exponential function? I've always thought of a model as an experimental tool to predict behavior. So it seems they are asking for a tool to predict the behavior of an exponential function, in which it seems they are asking to create a function that will accept a logarithmic "argument" and return an exponent.

Answer 7

In which case it would be C. Because it seems A would accept an exponent and return a value. At least we can see there are only two equations with base 11.

Answer 8

IF the problem read..
" If Ken wanted to create [REMOVED] an exponential function with base of 11 [REMOVED] , how would he set up his function? "

Then we might think it was A... but the question has this other extraneous information in it.

Answer 9

Does anyone else have any opinions on what the question might be asking?

Answer 10

okay for the record, and anyone else who has the poor misfortune of having to deal with this vague, ambiguous, error riddled, curriculum, there are 2 questions in the module that are phrased like this, and in both cases they mean for you to select the
f(x) = b^x
exponential form of equation.

Answer 11

so the answer is A - confirmed
