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

Name the most appropriate metric unit for each measurement

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

Which statements describe the solutions to the inequality x< -20 check all that apply. there are infinite solutions. each solution is negative. each solution is positive. the solutions are both positive and negative. the solutions contain only integer values. the solutions contain rational number values.
