The domain of t(x) = -3.8x - 4.2 is {-3, -1.4, 0, 8}. What is the range?

  • Math - ,

    plug each x into your equation and the answer for each is your range (y-value)

    I'll do one
    -3.8x - 4.2 for x = -3
    y = -3.8(-3) - 4.2
    y = 11.4 - 4.2
    y = 7.2

    so y = 7.2 is incl. in the range
    repeat for each x value

    idk
