4 marks · Normal

A table shows two separate algebraic fractions for different values of :

Values for \( f(x) = \frac{3}{x} \) and \( g(x) = \frac{x}{2} \)
xf(x)g(x)
23/21
43/42
61/23

Marking points

M1 · 1 mark · Correctly finds the sum for at least one value with working.

A1 · 1 mark · Finds the correctly simplified answers for all three values.

M2 · 1 mark · Shows working with fractions.

A2 · 1 mark · All answers written as fully simplified fractions.

Worked solution

Completed values for \( h(x)=f(x)+g(x) \)
xh(x)
2\frac{3}{2} + 1 = \frac{5}{2}
4\frac{3}{4} + 2 = \frac{3}{4} + \frac{8}{4} = \frac{11}{4}
6\frac{1}{2} + 3 = \frac{1}{2} + \frac{6}{2} = \frac{7}{2}
