Answer:
18.96 / 12 = 1.58
1.58 = the cost of 1 rose
1.58 X 5 = $7.9
A. 1 only- this study provides evidence that taking B12 vitamin daily contributed to protecting against Alzheimer’s disease.
With the first one, you just plug the numbers inside the parentheses into f(x). Therefore:
f(-2)=40
f(-1)=18
f(0)=8
f(1)=10
f(2)=24
For the second one, you look at the table and find where x=1. The number there is 24, so therefore, f(1)=24
Depends
it can be a trinomial example
(x-3)(x-4)=x²-7x+12
it can be a binomial example
(x-3)(x+3)=x²-9
