Answer

The range of the t(x)=-3.8x-4.2 is {7.2, 1.12,-4.2,-34.6}

Work Step by Step

To find the range of the t(x)=-3.8x-4.2 for domain of {-3,-1.4,0,8} you just have to plug in the domain into the function and find t(x) t(-3) = -3.8(-3) - 4.2 = 11.4 - 4.2 = 7.2 t(-1.4) = -3.8(-1.4) - 4.2 = 5.32 - 4.2 = 1.12 t(0) = -3.8(0) - 4.2 = 0 - 4.2 = -4.2 t(8) = -3.8(8) - 4.2 = -30..4 - 4.2 = -34.6
