Consider a proposition given as:
"$x \geq 6$, if $x^2 \geq$ 25 and and its proof as:
If x $\geq$ 6, then $x^2 =x.x \geq 6.6 = 36 \geq 25$
Which of the following is correct with respect to the given proposition and its proof?
- The proof shows the converse
- The proof starts by assuming what is to be shown
- The proof is correct and there is nothing wrong
- a only
- c only
- a and b
- b only
