Question 3 Express the following system of equations in matrix form and solve it using row operations. 3x - 4y-6z=1 7x+2y+z=2 15x + y - 3z = 2. Question 4 Determine the following integrals: 5x-3 J3x2-5-2 dx Question 5 The function fis given by In (4x) dx x3/4 S f(x, y) = 6xy4 - 3x² - 12y² +8. Determine the critical (or stationary) points off and determine the nature of each. Question 6 Use the Lagrange multiplier method to find the values of x and y which maximise the function f(x, y) = x3/41/4 subject to the constraint 3x + 2y = 64.
