Question 5

The gradient of the curve is zero at which of the following values of

a)		and		b)
c)				d)

 

Not correct. Choice (a) is false.

Try again, this is where the function is zero, not where the gradient is zero.

Your answer is correct.

so when

Not correct. Choice (c) is false.

Try again, 6 is the -intercept.

Not correct. Choice (d) is false.

Try again, this is the gradient function but doesn’t answer the question.
