Explain the transformation

y= 4 ( x+ 5) ² +3

• Wider, right 5, up 3

• Thinner, left 5, up 3

• thinner, right 5 up 3

• wider, left 5, up 3

in the formula y= a(x-h)² +k

the -h does what to the parabola ?

• Moves it horizontally - right or left

• Moves it opposite direction - horizontally Right or Left

• moves it vertically

• Makes it wider ( shrink)

in the formula y= a(x-h)² +k

the +k does what to the parabola ?

• moves it opposite Up - or Down +

• Moves it up + if positive or Down - if negative

• moves it right or left opposite

• makes it thinner ( stretched)
