A function is a rule that relates inputs to outputs.It takes elements from the domain and relates them to the codomain. It relates each element of a set with exactly one element of another set. In the graph, we see a single element of a set being mapped to different codomain. Thus, the graph does not represent a function
That wouldnt make sense if .4 is a decimal

Which number is the best estimate of 866,214,000,000 using powers of 10
a) 9 × 10¹¹
b) 8 × 10¹¹
c) 10 × 11¹⁰
d) 8 × 10-¹¹
Answer:
a) 9 × 10¹¹
Step-by-step explanation:
When we want to estimate a number using the power of 10, we are trying to write the number in a standard form.
We are to estimate :866,214,000,000 using powers of 10
Hence,
8.66214000000 × 10¹¹
We round up to the nearest whole number
= 9 × 10¹¹
Therefore, the best estimate for 866,214,000,000 using powers of 10
= 9 × 10¹¹
So 33 rounds to 30, because 3 is less than 5. 89 rounds to 90, because 9 is greater that 5.
then do this:
30
+90
____
120
120 is your answer! I hope I helped you!
