Example Calculation

Let’s go through an example using the calculator:

Function: f(x)=x2+3x−5f(x) = x^2 + 3x – 5f(x)=x2+3x−5
Approaching Value: x→2x \to 2x→2

Step 1: Substitute x=2x = 2x=2 into the function:f(2)=22+3(2)−5f(2) = 2^2 + 3(2) – 5f(2)=22+3(2)−5

Step 2: Solve the expression:f(2)=4+6−5=5f(2) = 4 + 6 – 5 = 5f(2)=4+6−5=5

Step 3: Result:
The limit as xxx approaches 2 is 5, which will be displayed instantly in the calculator.

  • Explore Limit Behavior: Try values slightly higher or lower than the approaching value to understand trends.

Common Scenarios You Can Solve

  • Polynomials: f(x)=x3−2x+1f(x) = x^3 – 2x + 1f(x)=x3−2x+1
  • Rational Functions: f(x)=(x2−4)/(x−2)f(x) = (x^2 – 4)/(x-2)f(x)=(x2−4)/(x−2)
  • Exponential Functions: f(x)=ex−1f(x) = e^x – 1f(x)=ex−1
  • Trigonometric Functions: f(x)=sin⁡(x)/xf(x) = \sin(x)/xf(x)=sin(x)/x (near x→0x \to 0x→0)
  • One-Sided Limits: Approach from left or right to study discontinuities
