Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease per unit
of x, to the nearest tenth of a percent.

y = 800 (1+

it's

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
