    an easy question

    question: Write an m‐file that returns the plot of y = 5 * sqrt ( k^0.5) over the range 1 ≤ k ≤ 5 in discrete increments of Δk = 0.5 as long as I y I< 8 .

    my m-file is;
    clc
    clear
    k=1: 0.5:5;
    y = 5 * sqrt ( k.^ 0.5)
    plot(k,y)

    Is that true? Is everything all right?

    It looks OK.

    Have you run it?

    Why do you have the side condition |y|<8 ?
