Question

I need help plz someone help me solved this problem I need help ASAP! I will mark you as brainiest!

Answer 1

Step-by-step explanation:

y = ${\log_b x}$

if x =4 then y = ${\log_b 4}$ =-1 --> $b^{-1}$ =4 --> b= 1/4

Answer 2

Answer:

b = 1/4

Step-by-step explanation:

It has to be a log because for x=0, b⁰ should be 1 for every b and that is not the case here.

Remember that $y = \log_bx$ means that $b^y=x$.

Since the point (4,-1) seems to be on the line, we can solve:

b⁻¹ = 4

so b = 1/4
