QUESTION 1
Which of the following has a positive discriminant?
a. f(x) = -(x + 5)2 - 3
b. f(x) = (x-3)
c. x) = (x+4)2 + 3
d. f(x) = (x + 3)2 - 6

answer should be  a

Step-by-step explanation:

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
