Which of the following values are in the range of the function graphed below?

Dafna1 [17]

Answer:

A. 1

Step-by-step explanation:

I see only one red function line in the graph. this line represents the simple function y = 1, for x in the interval [-2,1].

the domain of a function defines the possible values for x, and the range of a function defined the possible values for y.

this function has only one possible value for y : 1

so, only A applies.

What is the equation of this circle in standard form?

creativ13 [48]

Answer:

Option C.

Step-by-step explanation:

Note : In the given points one point is (8,-2) instead of (-6,-2).

The standard form of a circle is

$(x-h)^2+(y-k)^2=r^2$

where, (h,k) is center of circle and r is radius.

It is given that center of the circle is (-1,-2). So,

$h=-1,k=-2$

$(x-(-1))^2+(y-(-2))^2=r^2$

$(x+1)^2+(y+2)^2=r^2$ ...(1)

It is given that the circle passing through the point (8,-2),(-1,5),(6,-2),(-1,-9).

Substitute x=6 and y=-2 in equation (1).

$(6+1)^2+(-2+2)^2=r^2$

$(7)^2+(0)^2=r^2$

$49=r^2$

Substitute $r^2=49$ in equation (1).

$(x+1)^2+(y+2)^2=49$

Therefore, the correct option is C.

²-6x +10 is to be written in the form (x-p)² +g. Find the values of p and q.

Firlakuza [10]

Answer:

$p = 3\\\\q= 1$

Step-by-step explanation:

$x^2 -6x +10\\\\=x^2 -2 \cdot 3x +3^2 -3^2 +10\\\\=(x-3)^2 -9+10\\\\=(x-3)^2 +1\\\\\text{By comparing with}~ (x-p)^2 +q, \\\\p = 3\\\\q = 1$
