For the function, f(x)=2x+1, which outputs match the inputs
1 answer:
See the explanation
<h2>Explanation:</h2>Here you haven't provided any options, so I'll give you some inputs and outputs. Remember that the input of a function is called the domain, that is, all the x-values for which the function is defined while the output is called the range, that are all the y-values for which the functions is defined. Therefore, this table shows some inputs and outputs for the function:
Input (x) Output f(x)
-3 -5
-2 -3
-1 -1
0 1
1 3
2 5
3 7
For finding each output, just replace x by the corresponding value and you'll get f(x). For instance:
