Question

derivative of function y = x^3

Answer 1

Answer:

Example. The equation of a tangent to a curve.

a) Calculate the slope of the line that is tangent to y = x2 at the point

a) on the curve where x = 4.

b) What is the equation of that line?

Solution.

a) The slope of the tangent to the curve at x = 4 is the value of the

a) derivative at x = 4. The derivative of y = x2 is 2x. Therefore at
