The pH of a solution is a measure of how acidic it is. The greater the acidity, the lower the pH. The
function f(x) = -log x gives the pH of a solution,
where x is the concentration of hydrogen ions, in
moles per liter.
The graph of f(x) = -log x is a
✓ of the graph of
g(x) = log x

Yuh yeet honestly idk

4if you add the absolute values together

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
