Answer:
a) -2 and 4
b) function 2
Step-by-step explanation:
a)
rate of change is rise over run: change in y / change in x.
function 1:
- i will use first 2 pairs of data
- change in y: 5 - 3 = 2
- change in x: -2 - (-1) = -1
-rate of change = 2/-1 = -2
function 2:
- same idea, but find two points on the graph!
- (0,4) and (-1,0) for example! pick easy points
- change in y is 4. chabge in x is 1
- rate of change is 4
b)
function b has greatest rate of change. 4 > -2

square has 4 equal sides
so A = 144 = 12^2
A = L x W
= W. W
= W^2
12^2 = W^2
so W = 12
answer: one side of the square = 12
C = 11*(2*d) Try it and see that it fits every sample you have. Again this can be simplified to
C = 22 * d
