Sample questions with model answers

Every question in the paper gets a full exam-length answer in the app — organised by marks, the way a topper writes it.

5 marks Long answer

If f : R → R is defined by f(x) = 1 + x^2, then show that f is neither 1-1 nor onto.

Show answer outline

f is not 1-1 because f(x) = f(-x) and not onto because f(x) >= 1.

5 marks Long answer

For the matrices A = [2, 4; 1, 3; 6, 5], verify that (AB)' = B'A'.

Show answer outline

Use properties of transposes to verify.

5 marks Long answer

Solve the system of linear equations by matrix method: 2x + 3y + 3z = 5, x − 2y + z = −4, 3x − y − 2z = 3.

Show answer outline

x = 1, y = 2, z = 0.

5 marks Long answer

Integrate 1/(x^2 + 1) with respect to x and hence find ∫(x^2 + 2x + 10)dx.

Show answer outline

Integral = arctan(x) + x^2 + 10x + C.
