Factorising
Odd, even or neither?
Is it a Function?
100
simplify 5x + 10 - 2x - 12
3x - 2
100
Evaluate f(x)=-3x if x=2
What is -6?
100
Factorise 2p + 6
2 (p + 3)
100
Odd, even or neither?
y = x2
even
100
Is it a function?
{(2, 3), (4, 5), ( -2, 6)}
What is YES because x does not repeat?
200
Simplify 2y x 5y2
10y3
200
Evaluate f(x)=2x+1 if x=-2
What is -3?
200
Factorise -x2 - 5x
-x(x - 5)
200
Odd, even or neither?
y = x3
odd
200
Using the vertical line test does the graph of the points (1,3) and (1,5) represent a function?
What is False, the points fail the vertical line test

What is -9?
300
Factorise m2 + 5m + 6
(m+2)(m+3)
300
Odd, even or neither?
even
300
Is it a function?
| x | y |
| 2 | 4 |
| 1 | 5 |
| 2 | 6 |
What is NO because x repeats?
400
