Key Calculus Terms and definitions covered in this textbook
  • Direct variation

    See Power function.

  • Exponent

    See nth power of a.

  • Histogram

    A graph that visually represents the information in a frequency table using rectangular areas proportional to the frequencies.

  • Horizontal line

    y = b.

  • Implied domain

    The domain of a function’s algebraic expression.

  • Inverse tangent function

    The function y = tan-1 x

  • Invertible linear system

    A system of n linear equations in n variables whose coefficient matrix has a nonzero determinant.

  • Linear factorization theorem

    A polynomial ƒ(x) of degree n > 0 has the factorization ƒ(x) = a(x1 - z1) 1x - i z 22 Á 1x - z n where the z1 are the zeros of ƒ

  • Local maximum

    A value ƒ(c) is a local maximum of ƒ if there is an open interval I containing c such that ƒ(x) < ƒ(c) for all values of x in I

  • Logarithmic form

    An equation written with logarithms instead of exponents

  • Lower bound for real zeros

    A number c is a lower bound for the set of real zeros of ƒ if ƒ(x) Z 0 whenever x < c

  • Maximum r-value

    The value of |r| at the point on the graph of a polar equation that has the maximum distance from the pole

  • Minute

    Angle measure equal to 1/60 of a degree.

  • Natural exponential function

    The function ƒ1x2 = ex.

  • Number line graph of a linear inequality

    The graph of the solutions of a linear inequality (in x) on a number line

  • Placebo

    In an experimental study, an inactive treatment that is equivalent to the active treatment in every respect except for the factor about which an inference is to be made. Subjects in a blind experiment do not know if they have been given the active treatment or the placebo.

  • Power regression

    A procedure for fitting a curve y = a . x b to a set of data.

  • Quadratic formula

    The formula x = -b 2b2 - 4ac2a used to solve ax 2 + bx + c = 0.

  • Reciprocal function

    The function ƒ(x) = 1x

  • Rectangular coordinate system

    See Cartesian coordinate system.
