No, it is a linear function.

Step-by-step explanation:

Let's select values for X, and find the corresponding Y values:

X = -3, Y = 8.5

X = -2, Y = 7

X = -1, Y = 5.5

X = 0, Y = 4

X = 1, Y = 2.5

X = 2, Y = 1

X = 3, Y = -0.5

So our coordinates are:

(-3, 8.5) ; (-2, 7) ; (-1, 5.5) ; (0, 4) ; (1, 2.5) ; (2, 1) and (3, 0.5)

Graph these on a chart to visualize:

(In picture)

We can see that this is a decreasing linear function, <em>not</em> quadratic. Quadratic functions create a symmetrical curve, which this is not.

Answer:

B

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 7)² + (y - 5)² = 16 ← is in standard form

with centre = (- 7, 5 ) and r = \sqrt{16} = 4 → B

     Long division:   (x³ + 2)  ÷  (x + 1)


                                        <u>    </u><u>x² –  x  +  1   </u>
      x³ + 0x² + 0x + 2      |    x  +  1

                    +  x + 2
<span>                   </span> <u>–  x – 1</u>
                            + 1


         Quotient:   Q(x) = x² – x – 1;
  
     Remainder:   R(x) = + 1.
