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
