The set of natural numbers
Answer:
f(-1)= -5
Step-by-step explanation:
f(x) = -3x - 8
= -3(-1)-8
= 3-8
f(-1) = -5
The y intercept is when x=0, the x intercept is when y=0
so you two points are: (0, 3) and (-1, 0)
the slope is: m=(0-3)/(-1-0)=3, you y intercept(b) is 3
y=mx+b=> y=3x+3
I don't know about the top half but I know the bottom half. P.S. I'm sorry
