Please help with questions 2,3, and 4

2) d

3) c

4) d

Step-by-step 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
