Is this calculus or simple reasoning?

If the latter:

(3x+1)^1/2=8

square both sides

=3x+1=64

=3x=63

x=63/3

x=21

Use a graph of f or some other method to determine what, if any, value to assign to f(a) to make f continuous at x = a. HINT [See Example 2.] (If there is no such value, enter NONE.)

f(x) =

x^2 + 11x + 18/x + 2

; a = −2
