Answer 1

Hi there!

$\large{lim_{x \longrightarrow 3}( - 5 {x}^{2} - 2x + 4)}$

Simply substitute x = 3 in the expression.

$\large{ - 5 {(3)}^{2} - 2(3) + 4} \\ \large{ - 5(9) - 6 + 4} \\ \large{ - 45 - 6 + 4} \\ \large{ - 47}$

Questions can be asked through comment.

Furthermore, limit is like substituting a value. Note that limit is about an approaching value. This is a basic limit.

Hope this helps, and Happy Learning! :)
