Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=21(1.08)^x

3-12. write each answer with a reasonable number of figures. find the absolute uncertainty and percent relative uncertainty for each answer. (a) [12.41 (±0.09) + 4.16 (±0.01)] x 7.068 2 (±0.000 4) =? (b) [3.26 (±0.10) x 8.47 (±0.05)] - 0.18 (±0.06) =? (c) 6.843 (±0.008) x 104 + [2.09 (±0.04)- 1.63 (±0.01)] =?

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.
