Find stretching factor , period & asymptotes

Sketch two periods of the graph of the function h (x) = 4 sec ( # (x + 1) ) . Identify the stretching factor, period, and asymptotes. Enter the exact answers. Stretching factor = Number Period: P = Enter the asymptotes of the function on the domain [- P, P]. To enter 7, type Pi. The field below accepts a list of numbers or formulas separated by semicolons (e.g. 2; 4; 6 or x + 1; x - 1). The order of the list does not matter. Asymptotes: x
