A 06 ml dose of a drug is injected into a patient steadily f

A 0.6 ml dose of a drug is injected into a patient steadily for 0.5 seconds. At the end of this time, the quantity, Q, of the drug in the body starts to decay exponentially at a continuous rate of 0.6 percent per second. Using formulas, express Q as a continuous function of time, t, in seconds.
Q(t)= _______ if 0 <(or equal to)t< (or equal to)______?
and Q(t)=_____ if ______<(or equal to) t <(or equal to) infinity

(If you write your function without breaking it up, use an endpoint of infinity and enter none for the remaining answer blanks.)
