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
Well, 6/8 can be simplified: divide the numerator and denominator by 2, then your simplified fraction is 3/4. Now, multiply straight across: 4 times what=12? 3 does. So, you do the same thing to the numerator, because whatever you do to the denominator must be done to the numerator, and same reversed. 3*3=9, so the answer to this is 9/12!!
