Let y = f(x)
y = ln(3x)
Exchange place with x and y.
x = ln(3y)
Solve for y.
y = (e^x)/3
Replace y with the inverse notation.
f^(-1) x = (e^x)/3
Done.
Equal because 30 is the median and when you find the mean, it is also 30. Please give brainliest!
Answer:
g(f(4)) = 9
Step-by-step explanation:
Fill in gf(x) for where x is in g(x): (x-7)²
Then, fill in 4 for where x is: (4-7)²
Square it: (-3)²
9
12, because 150/25=6x2 is 12
Answer:
$1,800 was withdrawn because 18 * 100 = 1,800
