A function is defined as a set of points for every x-value, there is only one y-value.
So, you can't have two y-values for every x-value.
Thus, (B) would be a relation, because x = 7 has two y-values, and as such, doesn't satisfy the condition of a function.
Answer:
Your answer would be B.
Step-by-step explanation:
Hope this helps!
Let y = (b)ˣ
1) if b> 0, then growth, whatever the value of x>0
2) if b< 0, then decay, whatever the value of x >0
3) if b<0, then decay, whatever the value of x >0
4) if b<0, then growth, whatever the value of x <0
The sin graph starts at zero,
so the 2nd equation is really the first equation in disguise.
since both equations are the same, that means if you graph them, is just one line pancaked over the other, and the solutions points is every single one on each, namely
infinitely many solutions.
