Differentiate it
y' is also known as the gradient function. so when x = a, the gradient would be equal to? substitute x = a for all x values
therefore, the slope of the tangent is equal to
Find the slope of the tangent to the curve
y = 3 + 4x^2 - 2x^3
at the point where x = a.
Answer: 8a - 6a^2
I have no idea how to answer this question since it doesn't give me any points to work with.
Any help would be greatly appreciated!
Thanks in advance!
