Question

If Kim wanted to create a function that modeled an exponential function with base of 7 and what exponents were needed to reach specific values, how would she set up her function? f(x) = x7 f(x) = 7x f(x) = log7x f(x) = logx7

Answer 1

Your answer is f(x) = log₇(x) hope this helps

Answer 2

Answer:

$f(x) = x^7$

Step-by-step explanation:

Given that Kim wanted to create a function that modeled an exponential function with base of 7

So the appropriate function would be

$y=7^x$

which is exponential with base 7, passing through (0,1) and have range as only positive values of y.

y=0 will be an asymptote for this graph.

Other functions are wrong because

$f(x) = x^7$ is a polynomial funciton and not exponential

Similarly $log_{7} x$ is a logrithmic funciton and the next also

Hence right answer is option 2.
