## Step-by-step to find function values from the calculator

If you want to find function values from the calculator, you should follow the below general steps:

- Enter the equation of the function into the calculator. Make sure to use the correct format and notation for the calculator you are using.
- Input the value of the point at which you want to evaluate the function. For example, if you want to find the value of the function at \(x = 3\), you would input \(“3” \) into the calculator.
- Press the \(“=”\) button or the “enter” button to evaluate the function at the given point. The calculator should display the value of the function at the given point.
- Make sure to check the domain of the function before evaluating it, some functions are not defined for certain values of \(x\).

Please note that the process may vary depending on the type of calculator you have and its capabilities. Some calculators have built-in functions for common operations such as trigonometric or logarithmic functions, whereas others may require you to input the equation in a specific format. It’s always a good idea to refer to the calculator’s user manual for specific instructions.
