If y=6x3 +2x(-2) - x(-3), find dy/dx .
A.
dy/dx=15x2 -4x(-2) - 3x(-2)
B.
dy/dx = 6x + 4x(-1) - 3x(-4)
C.
dy/dx=18x2-4x(-3) + 3x(-4)
D.
dy/dx=12x2 + 4x(-1)-3x(-2)
Correct Answer: dy/dx=18x2-4x(-3) + 3x(-4)
Explanation
y = 6x3 +2x(-2) - x(-3) dy/dx = 18x2 −4x(−3) + 3x(−4)
y = 6x3 +2x(-2) - x(-3) dy/dx = 18x2 −4x(−3) + 3x(−4)THIS WEEK's
