Use the quotient rule to find the derivative of the function. y= 3x+1 8x+7 What is the correct way of writing the derivative of y? d (8x+7). (3x+1)- (3x+ dx dx + 1). (8x+ d (8x+7) ○ A. y' = [(8x+ +7)]² d d (8x+7) • О в. dx (3x+1)− (3x+1)• ¯dx (8x+7) y' = -(3x+1) O C. y=- (8x+7) ○ D. y' = d -(8x+7)• dx [(8x+ +7)]² [(8x+7)]² (3x+1)
