Answer:
Function 1
Step-by-step explanation:
Function 1:
[tex]y=\dfrac{5}{6}x+10[/tex]
The rate of change of the function 1 is:
[tex]\dfrac{5}{6}\approx 0.83[/tex]
Function 2:
The rate of change of the function 2 is:
[tex]\dfrac{15.75-14.25}{1-(1)}=\dfrac{1.5}{2}=0.75[/tex]
Hence, the greater rate of change has function 1.
