Using function concepts, it is found that the correct option is given by:
a.Yes, this graph represents a polynomial. There are two turning points and the least degree possible is three.
<h3>What is the least degree possible of a polynomial?</h3>
Supposing a polynomial with n turning points, the least possible degree is of n + 1.
In this problem, the polynomial has 2 turning points, hence the least possible degree is of 3 and option a is correct.

Answer:
x=-5, 5
Step-by-step explanation:
Because there is absolute value symbol and is equal to 5.
The distance travelled by the car will be 3.6km in 2 minutes.
<u>Explanation:</u>
Given:
Speed, s = 108 km/hr
s in km/min = ?
1 hr = 60 min
So,
108 km/hr = 
= 1.8 km/min
time, t = 2 min
Distance, d = ?
We know:
distance = speed X time
Therefore, the distance travelled by the car will be 3.6km in 2 minutes.
