A curve is given by the equation # y = (2x ^ 3)/3 - (7x ^ 2)/2 + 2x + 5 a . Determine the coordinates on the curve where the gradient is -3. b . Find the interval of values of x for which the curve is decreasing .

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

It’s c. i’m almost sure
