You can put this solution on YOUR website!
For example k(x)=x+9. I need to find 5 function values to this equation.
But what i am not understanding is where or how to find values for x?
:
You just assign a value for x, then do the math to get k(x)
For example, if x=-3
k(-3) = -3 + 9
then
k(-3) = 6
Assign a value of -1
k(-1) = -1 + 9
k(-1) = 8
:
Assign 3 more values, like x=0, x=2, x=3, and do the same thing
:
Response to student question, a graph of this equation. y = k(x)
