Question 15226: Can you please help me understand this question i really do not understand it:
y = 4x + 3. The question on it says to create an input and out put table using 0, 1, 2, and 3 as a domain.
Answer by wgunther(43) (Show Source): You can put this solution on YOUR website!
y= 4x+3
input/output table is just a table that shows values for certain x's. x is the independent variable, and y is the dependent variable, because what we plug in for x yeilds the y. Domain is the numbers that we can plug into x, and the range is the values we can get out of y. The table looks something like this
x | y
-----
0 | 3
1 | 7
2 | 11
3 | 15
so you can see, I'm just plugging in values for x and getting the y. if you let f(x)=y then you can see
f(x) = 4x+3
x | y
-----
0 | f(0)=3
1 | f(1)=7
2 | f(2)=11
3 | f(3)=15
