=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.
