Graphing Vhapter 6 +

Question 1

Remember about y =x^n graohs

Answer 1

Always flat with point if inflection still 0 0and can look weird

X4 is u

Question 2

Reciprocal graphs?

Answer 2

These are inversely proprtional y= k/x

They look like symmetrical and if it is - then other quadrants

Question 3

Dreictly vs indirectly proprtional

Answer 3

Y=kx , y= k/x

Remember - flipsmit

Question 4

Trandifkstions

Stretch

Answer 4

Vertical so anything + is + in y

Anything in the x bracket is oppsite

2) anything multiplying whole equation by a is y stretch
- anything multiply them x bracket I’d oppsite of that x stretch

3) again - a is reflection in x and - in bracket is reflection in y

Question 5

How do trigonometric graohs get affected

Answer 5

If it is y= sin2x, then everything is halved, and including the PERIOD. So it only rohestes every 180 now not 360

Question 6

How does y = 1/x2 look like

Answer 6

Both reciprocals in top two quadrants

Question 7

And how would y = 1/(x+k)2 look like

Answer 7

A horizontal translation of -k of the graoh y= 1/x2

Question 8

Remmeber ti show the roots and intersections esdpailky FATER TRANSLATIONS !

Question 9

If you want to multiply thr ckntents of one factor by 2 what also kust you do

Answer 9

Multiply the contents of the other factor by 2 aswell

Question 10

Watch out for mainting thr y axis , make sure youninckude a factor in the outside when needed
