b) Relative frequencies of each animal type
Dog: 4/10 = 0.4
Cat: 3/10 = 0.3
Fish: 2/10 = 0.2
Hamster: 1/10 = 0.1
c) Popularity
Dog is the most popular because it has the highest relative frequency.
Hamster is the least popular because it has the lowest relative frequency.

Answer:
2
Step-by-step explanation:
f(-1)=2(-1)+2+1
f(-1)=-2+2+1
f(-1)=1
f(0)=2(0)+2+1
f(0)=0+2+1
f(0)=3
Use slope formula for the average rate of change.
(y2-y1)/(x2-x1)
(3-1)/(0+1)
(2)/(1)

Answer:
When n=3 and x=−2 the answer is 11.
Step-by-step explanation:
Given:
Let p (n,x) be the function such that
To Find:
p (n,x) = p ( 3, -2) = ?
Solution:
Substituting n = 3 and x = -2 we get
Negative square gives positive number therefore (-2)²=4
When n=3 and x=−2 the answer is 11.
