Answer:
2) d
3) c
4) d
Explanation:
2- the coefficient of the leading term (the x that has the highest degree) need to be + which is only found in d
so the answer is d
3- I just graphed the equations and then looked whether or not they have an axis of symmetry at x=1
a does have an axis of symmetry at x=1
b does have an axis of symmetry at x=1
c does not have an axis of symmetry at x=1
d does have an axis of symmetry at x=1
so the answer is c
4-
a is wrong bc the the coefficient of the leading term is - so it will open downward.
b is wrong bc it's vertex is actually equal to (2,50)
c is wrong bc it's axis of symmetry is actually equal to x=2
d is correct bc since the graph is opening downward it will have a max point
so the answer is d
