Y=8200(1.19)x given the exponential function, identify whether the change represents growth or decay, determine the percentage rate of increase or decrease.

Step-by-step explanation:

When the exponential term is (1+r)^x, the fractional rate of change is r. Here, we have 1.19^x, so ...

  1 +r = 1.19

  r = 0.19 = 19%

This is a positive value, so the change represents growth at a rate of increase of 19%.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
