x=   -3, -2, -1, 0, 1,  2, 3, 

f(x)=63, 8, -1, 0, -1, 8, 63

Notice that when the graph progresses from (- 2, 8) to (-1, -1)...it passes through the x axis for the first time....so this is one zero

And then (-1, -1)  to (0,0)  ......given the fact that we're not told that graph reaches a posiitive value before it progresses to (1, -1)....we have to assume that it only "touches" the origin....this means that, -- at a minimum- two more "zeroes" are added

And from (-1, -1)  to (2,8) it passes through the x axis once more....and a last zero is added

So...at a minimum,  the graph has a degree of 4  [ the fact that the graph just "kissses" the origin means that the actual degree could also be 6, 8, 10, etc.   When a graph  just touches the x axis, it means that 2n zeroes are added.......

Your second one is correct !!!

HAHAHA!!!!....Hey, Melody....was that pic taken while you were doing "Food Court Maths??"

(2/5) *12  =   24 / 5  =   4 + 4/5  =   4.8

x  =  1x    ....so....

4x + 1x

Can you do it now, PM????

x^3+4x^2−43^x−10  by  x−5 

5 [  1      4      -  43      -10 ]

              5         45        10

     ___________________

      1      9          2          0

The remaining polynomial  is   x^2 + 9x + 2

Place the point of the compass on point M and draw an arc, using a width for the opening of the compass that is greater than (1 / 2) MN.

Here's a  step - by - step demonstration :

2.89 per meter * 7.24 meters    ≈  £ 20.92

475 g =  .475 kg

So...unit price  =   Cost / Quantity

So

4.05 / 1.3  ≈  3.2  £  per kg

1.47 / .475  ≈  3.09  £ per kg

The second is better

OK, potatoeboy.....

BTW.....welcome  !!!

Chloe  contributes  =   792 - 110 - 250  =  432 £

So....she receives  [ 432 / 792 ] * 352  =  192 £
