Test 2. Curves with several terms

 1. Find the value of these when x = –1:

x² + 2x

 а)  2;      b)  –1;     

 c)  1;      d)  –2.

 2. Complete the table below then draw the curve

y = x² + 2.

 а)  (–3, 10), (–2, 6), (–1, 3), (0, 2), (1, 3), (2, 6), (3, 11);     
 b)  (–3, 11), (–2, 6), (–1, 3), (0, 2), (1, 3), (2, 6), (3, 11);     

 c)  (–3, 11), (–2, 6), (–1, 3), (0, 2), (1, 4), (2, 6), (3, 11);     

 d)  (–3, 11), (–2, 6), (–1, 3), (0, 2), (1, 3), (2, 5), (3, 11).

 3. Complete the table below then draw the curve

y = x² – 4.

 а)  (–3, 5), (–2, 0), (–1, –3), (0, –4), (1, –3), (2, 0), (3, 5);     

 b)  (–3, 5), (–2, 1), (–1, –3), (0, –4), (1, –3), (2, 0), (3, 5);     

 c)  (–3, 5), (–2, 0), (–1, –3), (0, –4), (1, –3), (2, 1), (3, 5);     

 d)  (–3, 5), (–2, 0), (–1, –3), (0, –4), (1, –3), (2, 0), (3, 7).
