The graphs defined as g(x) = ax2 + q and f(x) = kx – 4 both pass through (-2 ; 0) on the
x-axis. The y-intercept of g is (0 ; -5).
6.1 Write down the:
6.1.1 Equation of the asymptote of f (1)
6.1.2 Value of q (1)
6.1.3 Coordinates of the other x-intercept of g (1)
6.2 Determine the equation of:
6.2.1 g (2)
6.2.2 f (3)
6.3 Calculate the y-intercept of f. (2)
6.4 On the same system of axes, sketch the graphs of g and f. Show ALL the intercepts
with the axes and asymptote(s). (6)
