Final Answer:
The range of t(x) is {1.12, -4.2, -34.6, 7.2}. None of the given options is answer.
Step-by-step explanation:
To find the range of the function t(x) = -3.8x - 4.2, we need to evaluate the function for each value in the domain and determine the set of all possible output values.
The domain of the function is given as {-3, -1.4, 0, 8}. Evaluating the function for each of these domain values, we get:
t(-3) = -3.8(-3) - 4.2 = 7.2
t(-1.4) = -3.8(-1.4) - 4.2 = 1.12
t(0) = -3.8(0) - 4.2 = -4.2
t(8) = -3.8(8) - 4.2 = -34.6
Therefore, the range of the function t(x) is {1.12, -4.2, -34.6, 7.2}.
