given the following function and transformations just write the new equation
a) y=lxl stretch by 3, up 1 left 2 b) y=3x^4 up 1, reflect over the x axis

Respuesta :

a) y=lxl 

stretch 3 = 
y=3lxl 

up 1=
y=3lxl + 1

left 2=
y=3lx+2l + 1

y=
3lx+2l + 1

b) 
y=3x^4

up 1=
y=3x^4 + 1

reflect over x-axis=
y=-3x^4 + 1

y=-3x^4 + 1
