Practical Example
Let’s calculate a real example using the tool:
Function: f(x)=3×2+2x−5×2+4x+1f(x) = \frac{3x^2 + 2x – 5}{x^2 + 4x + 1}f(x)=x2+4x+13×2+2x−5
Direction: x→∞x → ∞x→∞
Steps:
- Input the function in the calculator.
- Select x→∞x → ∞x→∞ from the dropdown.
- Click Calculate.
Result:
The calculator returns: limx→∞3×2+2x−5×2+4x+1=3\lim_{{x→∞}} \frac{3x^2 + 2x – 5}{x^2 + 4x + 1} = 3x→∞limx2+4x+13×2+2x−5=3
This shows that as xxx increases without bound, the function approaches the value 3.
Tips for Accurate Calculations
- Always ensure your function is typed correctly. Misplaced operators can lead to errors.
