Evaluate the function for x=2 and x=7. The domain of t(x) = -3.8x– 4.2 is {-3, -1.4, 0, 8} What is the range.

-11.8, -30.8, and range is {7.2, 1.12, -4.2, -34.6}

Step-by-step explanation:

t(x)= -3.8x-4.2

Evaluate the function for

x=2 is t(x=2)=-3.8*2-4.2= -11.8

x=7 is t(x=7)=-3.8*7-4.2=-30.8

domain are the values of x and are {-3, -1.4, 0, 8}

the range are the values of y or values of t(x)

t(x=-3)= 11.4 -4.2 =7.2

t(x=-1.4)= 5.32 -4.2 =1.12

t(x=0)= -4.2

t(x=8)= -30.4-4.2= -34.6

so the range is {7.2, 1.12, -4.2, -34.6}
