Answer:
C. The graph would shift five units to the left.
Step-by-step explanation:
y = x² + 5x - 2
We can write this equation in the form
y = a(x - h)² + k
If you change the value of h, you are <em>translating the parabola horizontally</em>.
If you <em>increase h by five units, the graph shifts five units to the left</em>.
In the figure below, the red parabola represents the original equation.
The blue parabola shows the graph shifting five units to the left
(from x = -2.5 to x = -7.5) when you replace x by x + 5.
Answer:
The scale factor is not 2
Step-by-step explanation:
Given
See attachment for the dilated triangles
Triangle ABC is dilated through center point O to form triangle A'B'C'.
From the attachment, we have:
i.e. the distance from the center point to C
and
i.e. the distance from the center point to C'
The length of OC' is calculated using:
The scale factor (k) is then calculated by dividing OC' by OC
Hence, Tiffany's claim is incorrect.
