Plese gotta get right! let f(x)=7x3−2x−12 and g(x)=−3x3−8x2+10x . what is the function rule for (f+g)(x) ? (f+g)(x)=4x6−8x2+12x−12 ((my choice)) (f+g)(x)=4x3−12x2+8x−12 (f+g)(x)=4x6−8x2+8x−12 (f+g)(x)=4x3−8x2+8x−12

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)] =?
