Y1CH4 Graphs and transformation Flashcards
1
Q
Where would a positive cubic graph start from?
A
Bottom right
2
Q
If a root is repeated what happens on a graph
A
The lines touches then bounces off
3
Q
If a root is repeated 3 times what happens
A
The graph will come be straight for 1s then continue down or up
4
Q
Reciprocal functions
y = k/x
y = k/x^2
A
Standard on top right and bottom left
on top left and top right
Asymptote = 0
5
Q
If y = 4/x and y= 12/x is drawn where would they be
A
top right and bottom left
12/x higher than and lower than 4/x
asymptotes are = 0
6
Q
y = f(x) + a
A
Move in y axis
7
Q
y = f(x+a)
A
Move in x axis
8
Q
y = af(x)
A
stretch in y axis
9
Q
y = f(ax)
A
stretch in x axis (opposite)
10
Q
y = -f(x)
A
reflection in x axis
11
Q
y = f(-x)
A
reflection in y axis
12
Q
A
