Can someone help me find the distance between each pair of points round the answers to the nearest tenth if necessary please help with 2,4 show me how you get it and the answer please

I'm not really understanding this question can you give me some more info

a ≈ 172.05

step-by-step explanation:

the pictures.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
