Question 7 In this question, we are going to find the negative zero of the function h(x) = -12 + sin(x) -1 Q7(a) Explain why 21 = 0 would be a bad choice when we want to find the negative zero of h(I). Q7 (b ) Use the IVT to verify that the negative zero of h(x) lies between -2.4 and -0.7. Q7 (c) Determine which is a better value for 1: 21 - -2.4 OR X1 - -0.7. and justify your choice (give an explanation). Q7(d) Using your choice for 1 from part Q7(c), find the value of the negative zero of h(r) correct to 4 decimal places
