The black graph is the graph of y=f(x). Choose the equation for the red graph.

Makovka662 [10]

Answer:

y-1 = f(x)

Step-by-step explanation:

Here, we want to choose the equation for the ref graph

The red graph as we can see is above the black

This means it is more positive

The difference between the two is just 1 unit

By the addition of 1 to the y-value of the black graph, we get the red

Thus, we have that;

y- 1 = f(x)

The vertex of the parabola below is at the point (-4,-2) wich of the equations below could be the one for this parabola

MrRissso [65]

The parabola with with a vertex at (-4,-2) represents any member of parabolas with the equation $y(x)=a(x+4)^2-2$ where $a$ is any real number with the exception that $a\neq 0$ .

The reason any equation of the form $y(x)=a(x+4)^2-2$ works is that there are an infinite number of parabolas with a vertex at (-4,-2). All of these parabolas are formed by applying some transformation that involves a vertical translation of -2 and a horizontal translation of -4 on the parabola $y=x^2$ . The different variations are archived by varying the constant $a$ . When $a$ is negative, the parabolas will face downwards. When $a$ is negative, the parabolas will be face downwards.
