Which graphs have domains that contain all real numbers ? (Help pls ! Due in 24 mins)

my answer was deleted because it was to vague the answer is 12.76 becuase its in the hundreths place. john

the formula for converting absorbance to transmittance goes as:

a = log (1/t)  a = 2 - log(%t)  10^a = 1/t  t = 10^-a  %t = 100(10^-a)

so at the given value of a,   a = 1.5

%t = 100(10^-1.5)

%t = 3.16%
