Given the function f:x ➡️ |x-3|, find the values of x such that f(x)=5​

Initially 100 milligrams of a radioactive substance was present. after 6 hours the mass had decreased by 4%. if the rate of decay is proportional to the amount of the substance present at time t, find the amount remaining after 24 hours. (round your answer to one decimal place.)

Asequence is defined recursively using the formula f(n + 1) =f(n) - 5. which sequence could be

If f(x) = 3x2 - 2x+4 and g(x) = 5x + 6x - 8, find (f-g)(x).
