How is the graph of y =(x-1)2 - 3 transformed to produce the graph of y = 5(X+4)??

lina2011 [118]

Answer:

<h2>The graph is translated left 5 units, compressed vertically by a factor of 5, and translated up 3 units.</h2>

Step-by-step explanation:

The initial function is

$y=(x-1)^{2} -3$

The transformed function is

$y=5(x+4)^{2}$

Notice that the first function represents a parabola with vertex at (1, -3), and the secong function represents a parabola with vertex at (-4, 0). That means the function was shifted three units up and 5 units to the left. Additionally, the function was compressed by a scale factor of 5, because that's the coffecient of the quadratic term.

Therefore, the right answer is the first choice.

What is the area, in square meters, of the figure below?

Veseljchak [2.6K]

Answer:

$0.55$ square meters

Step-by-step explanation:

The area of a triangle can be calculated by multiplying its height and base, then dividing the result by $2$ . As an algebraic expression, that would be $\frac{bh}{2}$ , where $b$ is the base and $h$ is the height. In this case, $b=2.2$ and $h=0.5$ . Therefore, the area of the triangle is:
