Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
kodGreya [7K]
In this questions, there are a few functions with more/less than and equal to symbol. 
1.  Answer: f(x)= 3
f(x)= 2<x ≤3
The x is [more than 2] and [less than 3] or [equal to 3]. The number that will fulfill the condition would be only 3 since 3 is [more than 2] and [equal to 3].

2. f(x)= 1
f(x)= 0<x ≤1
The x is [more than 0] and [less than 1] or [equal to 1]. The number that will fulfill the condition would be only 1 since 1 is [more than 0] and [equal to 1].


3. f(x)= x
f(x)= 1≤x ≤2
The x is [more than 1] or [equal to 1] and [less than 2] or [equal to 2]. The number that will fulfill the condition would be
1, since 1 is [equal to 1] and [less than 2] 
2, since 2 is [more than 1] and [equal to 2] 
The graph that follow the value would be: f(x)= x

4. Answer: f(x)= 4
f(x)= 3<x ≤4
The x is [more than 3] and [less than 4] or [equal to 4]. The number that will fulfill the condition would be only 4 since 4 is [more than 3] and [equal to 4].

Which equation in point-slope form contains the points (2, 6) and (–1, 3)?
Karo-lina-s [1.5K]
Using the formula for lines y=mx+b
To find out the gradient of the line, we do (y2-y1)/(x2-x1). 
(3-6)/(-1-2)= -3/-3= 1 is the slope of the line
So far, y=(1)x+b
Now substitute one of your given coordinates into this equation:
6=2+b
b=4
Therefore, the equation of the line is y=x+4
