Step-by-step explanation:
Answer:
The function is both injective and surjective.
Step-by-step explanation:
Given function,
We say a function is injective(one-one) when for every value of x we have a unique value of y.We say a function is surjective(onto) when the output y covers all the values of the co domain.
We know that in the graph of at no two points of x there can be a common y. So hence proved that is injective.
is also surjective because for x from - infinity to + infinity covers all the values in its co domain hence it is also surjecctive function.
X for the equations are:
1.-1.5
2.10
3.1.333
Answer:
Step-by-step explanation:
Hello!
The histogram summarizes the amount of sugar in organic snacks. (mg)
Y-axis shows the number of snacks
X-axis shows the amount of sugar per snack
The first column of the histogram show that 2 snacks contain sugar between 220 and 224 mg of sugar.
The second column shows that about 3 snacks have between 224 and 228 mg of sugar.
The third column shows that 8 snacks have between 228 and 232 mg of sugar.
The fourth column shows that 12 snacks have between 232 and 236 mg of sugar.
The fifth column shows that 11 snacks have between 236 and 240 mg of sugar.
The sixth column shows that 3 snacks have between 240 and 244 mg of sugar.
The seventh column shows that 2 snacks have between 244 and 248 mg of sugar.
The total of observations is 2+3+8+12+11+3+2= 41 snacks.
I hope this helps!
