Question

Determine f(x) from the table. The values from the table are given to the nearest ten thousandth:

Answer 1

@jimmyrep can you take a look at this one too?

Answer 2

sorry bob - got to turn in - its 2 am in uk and im really tired

Answer 3

This is an exponential function since f(0) = 1 (as the power function doesn't yield this)


So we can eliminate choice B. The answer must be either choice A or choice C


Now notice how as x increases, f(x) decreases. So this means that the answer must be choice C (because the negative exponent points to exponential decay)
