Answer 2

12

Answer 3

d/dx of (3(x^2)+3) = 6x

so at x=2, derivative 6*2=12

Answer 4

y=3x^2+3
dy/dx= 3 d/dx x^2+ d/dx 3
dy/dx = 3(2x)+0
dy/dx = 6x

at x=2
6*2=12

Answer 5

yeah 12 is correct like shristi1 showed

Answer 6

thanks ! : )

Answer 7

12 as dy/dx gives 6x which then produces 12

Answer 8

y=3x^2+3
dy/dx= d/dx(3x^2+3)
dy/dx = 3(2x)+0
dy/dx = 6x
at x=2
6(2)=12
Answer = 12
