To find the limit of a function using a calculator, you can follow these steps for a numerical approach:

Step 1: Enter the function into your calculator. Let’s say we have the function f(x) = 3x^2 + 5x – 2.

Step 2: Choose a value to approach the limit from. Let’s use an x-value of 1.

Step 3: Enter the value of x into the function. In this case, substitute x = 1 into f(x): f(1) = 3(1)^2 + 5(1) – 2 = 6 + 5 – 2 = 9.

Step 4: Select another value to approach the limit from. Let’s choose a smaller value, x = 0.9.

Step 5: Repeat step 3 with the new value: f(0.9) = 3(0.9)^2 + 5(0.9) – 2 = 7.77.

Step 6: For a more accurate result, select even smaller values of x (e.g., 0.99, 0.999) and repeat steps 3 and 5 to get closer to the actual limit.

Step 7: Observe the pattern in the values obtained for different x-values. As x approaches a certain value, if the output values approach a specific number, that number would be the limit of the function.

Limit calculations can also be done symbolically using algebraic techniques without a calculator. However, if you specifically want to find the limit using a calculator, this numerical approach can be followed.
