Ianswered this problem wrong on my calculus bc test. can you guys me figure out the correct answer?

if y = 3x^3 - 2x and dx/dt = 3 , find dy/dt when x = -2.

Step-by-step explanation:

It was given that;

When we differentiate this function with respect to x, we get;

When , we get;

Also we were given that;

.

Recall the chain rule;

We substitute these values into the formula to get;

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
