Here is a graph of a function.

Which of these statements is/are true?

1. The graph of the function has one relative maximum and one relative minimum.
2. The graph of the function has two inflection points.
3. The function has no zeros.
4. The range of the function is (??? , ?).

a) 2 and 4 only.

b) 1, 2 and 4 only.

c) None of the statements are true.

d) 2 only.

e) All of the statements are true.

f) None of the above.

Solution

1. function has relative max at x=-2 and relative min at x=+2

2. it ha two inflections because it changes sign attwo places

3. if any value substituted it never be zero

4. it assymptotus to infinity so it range must be in between -inf to +inf

all of the statements are true

ans is e
