Answer:

the answer is b

Step-by-step explanation:

so you can see the points 1,12 amd 2,17 and you want to find how much this goes up by because it is an arithmetic sequance. so if you go up by 5 everytime then the y-intercept where the line crosses the y-axis would be 0,7 or 7

What’s the remainder for this synthetic division problem?
Vesna [10]

3   |   1    5     -8     6

.    |         3    24   48

- - - - - - - - - - - - - - - -

.    |    1    8    16    54

That is to say,

\dfrac{x^3+5x^2-8x+6}{x-3}=x^2+8x+16+\dfrac{54}{x-3}

The remainder is 54.

Another way of doing it is to apply the polynomial remainder theorem, which says the remainder upon dividing a polynomial p(x) by x-c is exactly p(c). So recognizing that the listed coefficients refer to

p(x)=x^3+5x^2-8x+6

we find

p(3)=3^3+5\cdot3^2-8\cdot3+6=54
