F(x) = x^2 + 6x + 8
= b^2 - 4ac
= (6)^2 - 4(1)(8)
= 36 - 4(8)
= 36 - 32
= 4
g(x) = x2 + 4x + 8
= b^2 - 4ac
= (4)^2 - 4(1)(8)
= 16 - 4(8)
= 16 - 32
= -16
h(x) = x2 – 12x + 32
= b^2 - 4ac
= (-12)^2 - 4(1)(32)
= 144 - 4(32)
= 144 - 128
= 16
k(x) = x2 + 4x – 1
= (4)^2 - 4(1)(-1)
= 16 - 4(-1)
= 16 + 4
= 20
p(x) = 5x2 + 5x + 4
= b^2 - 4ac
= (5)^2 - 4(5)(4)
= 25 - 4(20)
= 25 - 80
= -55
t(x) = x2 – 2x – 15
= b^2 - 4ac
= (-2)^2 - 4(1)(-15)
= 4 - 4(-15)
= 4 + 60
= 64

Answer:
E). Using a representative sample helps to make survey data more reliable.
Explanation:
Surveys are characterized as the research method through specific data is gathered from a group in order to know people's opinions, thoughts, or any other kind of information like demography, behavior, etc.
As per the question, the statement '<u>employing a representative sample assists in enhancing the credibility of the survey</u>.' A representative sample is described as the subdivision of a population that precisely mirrors the attributes of a wide population. Thus, using such a subset would increase the credibility of the data collected, and thus, the deductions would be more reliable. Hence, <u>option E</u> is the correct answer.
