The y intercept would be -4 bc that that’s the only number that the line is hitting on the y line . y line goes up and down .
20-6=14
14+8=22
22*4=88
88+12=100
Hope this helps :)
the ones with straight lines are functions the ones that are curved is not a function
F(x) = x/4
so
f(-8) = -8/4 = -2
answer
f(-8) = -2
