Answer:
To graph [tex]y=ax^2[/tex], you stretch or compress the graph of [tex]y=x^2[/tex] vertically by a factor of a. If [tex]a < 0[/tex], the parabola is also reflected in the x-axis.
To graph [tex]y=ax^2[/tex], you stretch or compress the graph of [tex]y=x^2[/tex] vertically by a factor of a. If [tex]a > 1[/tex] or [tex]a < -1[/tex], the graph is stretched vertically by a factor of a.
To graph [tex]y=(x-h)^2[/tex], you translate the graph of [tex]y=x^2[/tex] horizontally h units. If [tex]h < 0[/tex], the graph is translated h units to the left.
#39
- y=x²
Then
- y=-ax² as a is negative
The parabola is reflected about x axis
#40
a>1 or a<-1
Theis should be vertically streched by factor a
*41
horizontal translation=hunits
So the graph is shifted h units left
