| Question 1 |
| |
The straight line with slope 3 passing through the point (1, –2) is |
|
|
|
y = 3x – 1 |
|
|
|
y = 3x 2 – 1 |
|
|
|
y = 3x 2 – 5 |
|
|
|
y = 3x – 5 |
|
|
|
|
|
| Question 2 |
| |

1) Is a parabola opening upwards.
2) Is a parabola opening downwards.
3) Crosses the x–axis at 1 and –3.
4) Crosses the x–axis at –1 and 3.
5) Has a vertex at x = 1.
6) Has a vertex at x = 2.
The true statements are: |
|
|
|
1, 3, and 6 |
|
|
|
2, 4, and 5 |
|
|
|

|
|
|
2 and 3 |
|
|
|
|
|
| Question 3 |
| |
The equation of the circle, center (3, –5) with radius 4, is |
|
|
|
(x – 3) 2 + (y + 5) 2 = 4 |
|
|
|
(x – 3) 2 + (y + 5) 2 = 16 |
|
|
|
(x + 3) 2 + (y – 5) 2 = 4 |
|
|
|
(x + 3) 2 + (y – 5) 2 = 16 |
|
|
|
|
|
| Question 4 |
| |
The curve y = x 3 – 4x crosses the x–axis at |
|
|
|
x = O, 4 |
|
|
|
x = –2, O, 2 |
|
|
|
x = O, 2 |
|
|
|
x = –2, 2 |
|
|
|
|
|
| Question 5 |
| |
The circle with radius 5, and center on the y–axis at y = 4, cuts the x–axis at |
|
|
|
x = –1, 1 |
|
|
|
x = –2, 2 |
|
|
|
x = –3, 3 |
|
|
|
Doesn't cut the x–axis. |
|
|
|
|
|
| Question 6 |
| |
The curves y = x 2 and y = x + 6 intersect at |
|
|
|
x = –3, –2 |
|
|
|
x = 2, 3 |
|
|
|
x = –3, 2 |
|
|
|
x = –2, 3 |
|
|
|
|
|
| Question 7 |
| |
The curves y = x 1/2 and y = –x + 6 intersect at |
|
|
|
x = 4, 9 |
|
|
|
x = 4 |
|
|
|
x = 9 |
|
|
|
They do not intersect. |
|
|
|
|
|
| Question 8 |
| |
The curves y = x 3 – 2x 2 and y = 2x 2 – 3x intersect at |
|
|
|
x = 1, 3 |
|
|
|
x = 3/2, 2 |
|
|
|
x = O, 1, 3 |
|
|
|
They do not intersect. |
|
|
|
|
|
| Question 9 |
| |
The curves (x – 1) 2 + (y + 1) 2 = 4 and y = 2x – 1 intersect at |
|
|
|
x = –3/5, –1 |
|
|
|
x = –3/5, 1 |
|
|
|
x = –1, 3/5 |
|
|
|
They do not intersect. |
|
|
|
|
|
| Question 10 |
| |
The curves x 2 + y 2 = 1 and y = x – 2 intersect at |
|
|
|
x = –1, 1 |
|
|
|
x = –2 |
|
|
|
x = 2 |
|
|
|
They do not intersect. |
