please help me solve

x- 9 Let f(x) = x+3 . (a) Calculate f(x) for each value of x in the following table. (b) Make a conjecture about the value of lim x- 9 *+-3X+3' (a) Calculate f(x) for each value of x in the following table. X -2.9 - 2.99 -2.999 -2.9999 - 9 f(x ) = x+3 X -3.1 - 3.01 -3.001 - 3.0001 . 9 f(x) = x+3 (Type an integer or decimal rounded to four decimal places as needed.) ave
