Give details on what life was like for the family after the fall of Saigon. The Eest we Could Do

Question 12 (SSSCE.July 2006 Ou 3) Two functions \( f \) and \( g \) are defined by \( f(x)=x^{2}+3 \) and \( g(x)=\sqrt{x-3} \), where \( x \in R \), the set of real numbers. a) State the domain of \( g \) b) Find fog \( (x) \) c) Determine whether or not \( f \) is one-to-one.

What pattern do you notice in problem 2? How could it help you solve a problem such as \( 297 \times 2 \) ?

QUESTION 4 Complete the table on the annexure provided for \( g(x)=-\cos x \). Round off your answers correct to one decimal where necessary. Use the diagram sheet provided and the completed table to draw neat sketch graph of \( g(x)=-\cos x \) for \( x \in\left[0^{\circ} ; 360^{\circ}\right] \). What is the amplitude of \( g(x) \) ? Determine the period of \( g(2 x) \).

d \( 4 \frac{11}{24}-1 \frac{13}{18} \)

1 Divide 150 in the ratio \( 2: 3 \). 2 Divide 72 in the ratio \( 2: 3: 4 \) 3 Divide 5 kg in the ratio \( 13: 7 \). 4 Divide 45 minutes in the ratio \( 2: 3 \). 5 Divide 1 hour in the ratio \( 1: 5 \).
