Answer:
y=log_2 (x)
Step-by-step explanation:
We see that the graph passes though the point (2,1). So we can write:
log_a (2) = 1 => a = 2
So it's a log in base 2.
For A, you take 70% of 421,000 and subtract that from 421,000. You should solve like this: 421,000 - (0.7 x 421,000).
For B, you take 40% of 31.50 and add it to 31.50. (31.50 + (31.50 x 0.4).
This is all I can give for now. Glad to help you!
