Question

How do you find the limit of `x^2` as x approaches `3^+`?

Answer 1

=`lim_(xrarr3^+) 9`

Explanation:

`lim_(xrarr3^+) x^2`

this is a simple limit problem where you can just plug in the 3 and evaluate. This type of function (`x^2`) is a continuous function that will not have any gaps, steps, jumps, or holes.

to evaluate:

`lim_(xrarr3^+) 3^2`

=`lim_(xrarr3^+) 9`

to visually see the answer, please see the graph below, as x approaches 3 from the right (positive side), it will reach the point (3,9) thus our limit of 9.
