can anyone please help me I am struggling?? It’s 9th grade algebra 1 average rate of change comparison

a) 2 b) 1 c) 7/6

Function a(x) = 2x + 3 has the greatest rate of change

Step-by-step explanation:

a(x) = 2x + 3

2(-1) + 3 = 1 (-1,1)

2(2) + 3 = 7 (2,7)

= 6/3

=2

b(x) = x^2 - 1

(-1)^2 - 1 = 0 (-1, 0)

(2)^2 - 1 = 3 (2,3)

= 3/3

=1

c(x) = 2^x + 1

2^(-1) + 1 = 1.5 (-1, 1.5)

2^(2) + 1 = 5 (2,5)

= 3.5/3 or 7/6

=7/6

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

the answer is 31.27mph
