The graphs of \(f\) and \(f^{-1}\) are reflections of each other in the line ________.

A nonrigid transformation of \(y = f(x)\) represented by \(h(x) = f(cx)\) is a ________ ________ if \(c > 1\) and a ________ ________ if \(0 < c < 1\).

A function \(f\) is ________ on an interval if, for any \(x_1\) and \(x_2\) in the interval, \(x_1 < x_2\) implies \(f(x_1) > f(x_2)\).

The function given by \( f(x) = \left\\{ \begin{array}{ll} 2x - 1, & \mbox{ \) x < 0 \(} \\ x^2 + 4, & \mbox{ \) x \ge 0 \(} \end{array} \right.\)

In Exercises 1-9, match each function with its name. \(f(x) = \sqrt{x}\) (a) squaring function (b) square root function (c) cubic function (d) linear function (e) constant function (f) absolute value function (g) greatest integer function (h) reciprocal function (i) identity function

The equation \( (x - h)^2 + (y - k)^2 = r^2 \) is the standard form of the equation of a ________ with center ________ and radius ________.

A nonrigid transformation of \(y = f(x)\) represented by \(g(x) = cf(x)\) is a ________ ________ if \(c > 1\) and a ________ ________ if \(0 < c < 1\).

A function \(f\) is ________ if each value of the dependent variable corresponds to exactly one value of the independent variable.

A function value \(f(a)\) is a relative ________ of \(f\) if there exists an interval \((x_1, x_2)\) containing \(a\) such that implies \(f(a) \geq f(x)\).

Direct variation models can be described as "\(y\) varies directly as \(x\)," or "\(y\) is ________ ________ to \(x\)."
