By dividing it by a number that = to it
Well if her simplifies 1 3/7 to 1 1/2 and 5 4/5 to 6 then he would be overestimating because 1 1/2 is greater than 1 3/7 and 6 is greater than 5 4/5
Hope this helps!
Answer:
No
Step-by-step explanation:
Definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output
Here we have more than one output for one input:
- x=-1 => y= -1, 0, 1
- x= 1 => y= 1, 2, 3
So this is not a function
Answer:The function v(x) has the largest value when x = 4.
Solution:
x=4;
e(4) = 4^2 + 6×4 + 21=16+24+21=61
m(4) = 8×4=32
v(4) = 31×4=124
v(4)>e(4)>m(4)
Therefore,The function v(x) has the largest value when x = 4.
