Has to equal 1 total - you already have 0.15+.2+.08, which is .43. so you have 1-.43 remaining, which is .57. since orange and yellow are the same, we'll call them x, so 2x = .57. divide both sides 2 to get x = .285. so you're correct

What is the logarithmic function modeled by the following table? x f(x) 9 2 27 3 81 4
Aliun [14]

Answer:

The logarithmic function modeled by the given table:

f(x) = log₃x

Step-by-step explanation:

Given Table:

x     f(x)

9     2

27    3

81    4

We can see that x increases as powers of 3. And f(x) is the power.

We assume that f(x) = log₃x

Checking using the table:

for x = 9

f(x) = log₃9 = 2

for x = 27

f(x) = log₃27 = 3

for x = 81

f(x) = log₃81 = 4

Hence proved.
