To calculate the output for the function rule 2x+3 with an input of 7, you substitute 7 for x, multiply by 2, and then add 3, resulting in an output of 17.
To determine the output using the function rule 2x+3, you need to substitute the input value into the function.
In this case, the input is 7.
Here's the step-by-step explanation:
- Start with the function rule: y = 2x + 3.
- Replace 'x' with the input value, which is 7: y = 2(7) + 3.
- Multiply 2 by 7 to get 14: y = 14 + 3.
- Add 3 to 14 to find the output: y = 17.
Therefore, when the input is 7, the output of the function y = 2x + 3 is 17.
