Wouldn't it be 2 since it goes into all them equally.
Answer:
20m
Step-by-step explanation:
Given the formula that modelled the height given as;
h=30+40t-5t^2
At t = 4s
h=30+40(4)-5(4)^2
h = 30+160-80
h = 160-60
h = 110m
At t = 2s
h=30+40(2)-5(2)^2
h=30+80-20
h = 110-20
h= 90m
Difference in height = 110-90 = 20m
Hence the height is 20m higher above the ground at 4s than at 2s
Answer:
C or D
dont get me wrong here im the wrong bc this is bassicly taking ur points but it c i think but d is still a good opition I think c

Step-by-step explanation:
Answer:
A function is a relation in which each input has only one output. In the relation, y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y.
Step-by-step explanation:
For every x there is exactly one y value. We can forgive a function if some values of x do not have a y, but if there is more than one y for even one value of x, then the relation is not a function.
