Question 7 of 10 f(x) = 1 + 7. Find the inverse of f(x) and its domain.
O A f(x) = 47 3, where x3
OB. f-'(x) = 7+3, where x# 3
O c. f '(x)= 7+3, where x#7
3, where x -7
Please help me please

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

the answer is 21%.
