Find the derivatives of the function y = 2x2(2x - 1) at the point x = -1

Assessment: JAMB UTME - Mathematics - 2004 Subject: General Mathematics

Question 1 Report

Find the derivatives of the function y = 2x2(2x - 1) at the point x = -1
Answer Details
y = 2x2(2x - 1)
y = 4x3 - 2x2
dy/dx = 12x2 - 4x
at x = -1
dy/dx = 12(-1)2 - 4(-1)
= 12 + 4
= 16
