PLEASE HELP ASAP!! ILL GIVE BRAINLIEST IF CORRECT
Natalka [10]

Answer:

Function 1 has a greater Y intercept than that of function 2

Step-by-step explanation:

Y intercept can be found by replacing x by 0 or

x = 0 0f the given function.

in this case Function 1 has a Y intercept of 5 when x =0

on the other hand, function 2 crosses the y axis once at -1 which is the y intercept.

you can now clearly see that

y = 5 > y = -1

---> 5>-1

so that's why we conclude that 1 has a greater Y intercept.
