**Convert to an exponential equation**

log_{9} = -2

**Determine whether the relation is a function.**

{(-5, -4), (-2, 9), (-1, -2), (-1, 7)}

**Determine whether the equation defines y as a function of x.**

x + y = 9

**Determine whether the given quadratic function has a minimum value or maximum value. Then find the coordinates of the minimum or maximum point.**

f(x) = -x^{2} – 2x – 6

**Simplify**

log_{2} 2^{5}

**Simplify**

log_{6} 1/36

**Simplify**

9^{log}_{9}^{(7)}
