    the function is continuous from the left at x=1 and continuous from the right at x=0

    Step-by-step explanation:

    a function is continuous from the right, when

    when x→a⁺ lim f (x) = f (a)

    and from the left when

    when x→a⁻ lim f (x) = f (a)

    then since the functions presented are continuous, we have to look for discontinuities only when the functions change

    for x=0

    when x→0⁺ lim f (x) = lim e^x = e^0 = 1

    when x→0⁻ lim f (x) = lim (x+4) = (0+4) = 4

    then since f (0) = e^0=1, the function is continuous from the right at x=0

    for x=1

    when x→1⁺ lim f (x) = lim (8-x) = (8-0) = 8

    when x→1⁻ lim f (x) = lim e^x = e^1 = e

    then since f (1) = e^1=e, the function is continuous from the left at x=1
