  1. Introductory calculus

    Evaluate a polynomial limit

    Use continuity to evaluate a polynomial limit by substitution.

  2. Introductory calculus

    Evaluate a rational limit with a removable hole

    Use factorization to evaluate a limit even when direct substitution gives 0/0.

  3. Introductory calculus

    Differentiate a power function

    Use the power rule on a constant times a positive integer power.

  4. Introductory calculus

    Use a derivative to find a tangent line

    Combine a derivative and a point on a quadratic curve to determine a tangent line.

  5. Introductory calculus

    Integrate a quadratic over an interval

    Evaluate a definite integral of a constant multiple of x².

AN EXAMPLE FROM THIS CHAPTER

Find the limit of 2x2 + (3)x + (1) as x approaches 2.

Show answer & explanation

15

Polynomials are continuous. Substitute x=2: 2(2)2 + (3)(2) + (1) = 15.
