Fill in the input output table for the function 𝑦 equals five 𝑥 plus three.
Your input values are the values that you plug in for 𝑥. So we’ll be plugging in zero, two, four, and five. Once we plug those input values in, we will get an answer which is what 𝑦 will be equal to. We will plug in 𝑥 and we will get an answer for 𝑦. That’s why it’s called an output. It’s like you plug in something in and out pops out an answer for 𝑦.
Here, we have our equation 𝑦 equals five 𝑥 plus three. We will plug in a value for 𝑥, the input, and we will get a value for 𝑦, the output, by using this function.
So we plug in zero. Five times zero is zero and zero plus three is three. So our output value for our input value of zero would be three.
Now we plug in two. Five times two is 10 and 10 plus three is 13.
Now we plug in four for 𝑥. Five times four is 20 and 20 plus three is equal to 23.
Finally, we plug in five for 𝑥. And five times five is 25 and 25 plus three is 28.
So now we have filled in the input output table for the function 𝑦 equals five 𝑥 plus three.
