The graph of function h is shown (in the picture) I'm fairly sure there supposed to connect, but they won't. Anyone know why?

[Original Equation: h(x) = {-x^2-6x-9 x<-2
{(1/3)^x -4 -2 ≤ x ≤ 2
{1/2x -4 x>2

Astandard deck of cards contains 52 cards. one card is selected from the deck. (a) compute the probability of randomly selecting a seven or king. (b) compute the probability of randomly selecting a seven or king or jack. (c) compute the probability of randomly selecting a queen or spade.

Aprojectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 704t. after how many seconds does the projectile take to reach its maximum height?
