The graph of the function f(x) = –(x + 3)(x – 1) is shown below.

Step-by-step explanation:

it is a downward parabola cutting x-axis at (-3,0),(1,0)

f(x)=-(x+3)(x-1)

=-(x²+2x-3)

=-(x²+2x+1-1-3)

=-(x+1)²+4

vertex is (-1,4)

step-by-step explanation:

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;
