Two linear functions are shown. Which function has the greater initial value?

we conclude that function A has a greater initial value.

Step-by-step explanation:

As we know that the initial value is obtained by setting x=0

so

Given the function A

From function A, it is clear that at point x=0, the value of y=8

i.e.

at x=0, y=8

Given the function B

substitute the value x=0 to get the initial value of function B

i.e.

at x=0, y=4

Therefore, we conclude that function A has a greater initial value.
