Answer:
Ummm i did 2a, 2b, 2c, and 3
Step-by-step explanation:
2a.
p(x)=4x - this is because the sides of a square is x, the perimeter is 4x
0->0, 1->4, 2->8, 3->12, 4->16, 5->20, 6->24
2b.
y=4x
2c.
plot the points (0,0), (1,4), (2,8), (3,12), (4,16), (5,20), and (6,24) then connect them, it should be a straight line
3.
f(x)=80-15x, when x is 2.5 you get 80-15(2.5)=42.5
A(x)=25+10x, when x is 2.5 you get 25+10(2.5)=50
50>42.5
therefore A(x)>f(x)
