Let $w_0=-4$ and $w_1=-3.$ After running gradient descent for one iteration suppose we end up Case $1$: $w_0=-3\mathrm{.}97$ and $w_1=-2\mathrm{.}98.$

Case $2$: $w_0=3\mathrm{.}97$ and $w_1=2\mathrm{.}98.$

a$)$ What do you think about learning rate $a,$ is it a well$-$chosen learning rate? $($Yes or No$)$

b$)$ If not, explain why?

c$)$ And how would you change $,$ would you increase it or decrease it$?($Increase or Decrease$)$

Give your answers to a$),$ b$),$ c$)$ for each case $1$ & $2$ seperately.
