Afunction t multiplies the input z by 2/3 and divides that by the quantity (z-1/2) .
write the function equation for t(z)

Thank you for posting you question here at . I hope the answer will help you. 

T (z) = 2/3z over z - 1/2
T(3) = 2/2.5 = 4/5 or 0.8
T(1/2) is indeterminate, he reason being that the denominator becomes zero. Division by zero gives an indeterminate result.

The answer for this is 9/1253decimal form 0.007
