Which polynomial function has a leading coefficient of 1 and roots (7 + i) and (5-1) with multiplicity 1? Of(x) = (x + 7)(x -)(x + 5)(x + 1)
Of(x) = (x - 7)(x - 1)(x - 5)(x + 1)
f(x) = (x - (7-1)(x - (5 + 1)(x - (7 + 1)(x -(5-1)
f(x) = (x + (7-1))(x + (5 + 1)(x + (7 + 1)(x + (5-1)

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

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;
