Yooo can somebody pls help I’ve been stuck on this for hrs, I’ll give you 10 or 20 points!

Step-by-step explanation:

I have no idea how to do the diagrams.

X-intercepts are the ROOTS!

(x+7)(x+3)

x = -7,-3

Y-intercept is just when x ='s 0 lol

y inter = 21

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

answer is 144
