Here's the solution to Question 4:

4.1 Write down the value of pp.

  1. Determine the value of bb for f(x)f(x).

    The function f(x)=x2+bx−3f(x) = x^2 + bx - 3 passes through the x-axis at (1;0)(1; 0).
    Substitute x=1x=1 and f(x)=0f(x)=0:

    0=(1)2+b(1)−30 = (1)^2 + b(1) - 3 0=1+b−30 = 1 + b - 3 0=b−20 = b - 2 b=2b = 2

    So, f(x)=x2+2x−3f(x) = x^2 + 2x - 3.

  2. Find the y
