Does each function describe exponential growth or decay?

drag and drop the equations into the boxes the correctly complete the table:

growth:

decay:

y= 1/2(1+0.3)^t

y= 0.3(0.95)^t

y= ((1+0.03)^1/2)^2t

y= 200(0.73)^t

y= 4(1/2)^t

(c) the diagram shows the first three shapes of a matchsticks arrangement.first shape = 3second shape = 5third shape = 7given m represents the number of matchstick used to arrange the n'th shape.(i) write a formula to represent the relation between m and n. express m as the subjectof the formula.(ii) 19 matchsticks are used to make the p'th shape. find the value of p.
