Find the instantaneous rate of change at the zeros for the function: y = x² - 2x² - 8x² + 18x-9 Mark Value: 2 If y = x 2, x= 3t+ 2 and t= 3k - 2, find an expression for y = f(k). Express y as a function of k if y= 2x+ 5, x= √√3t-1 and 1 = 3k - 5. 9. What is the domain off-g, where f(x) = √√x+1 and g(x) = 2log[- (x + 1)]? Mark Value: 2
