Question

Find a so that the graph of f(x)=log base of a argumentation x contains the point (1/2,-4)

Answer 1

HI!!

Answer 2

that means \[\log_a(\frac{1}{2})=-4\] right?

Answer 3

in equivalent exponential form, that tells you that \[\huge a^{-4}=\frac{1}{2}\]

Answer 4

can you solve that for \(a\)?

Answer 5

Yes thank you!!
