Question

Can someone please check my answer for this?
Use synthetic substitution to find g(4) for the function g(x)=x^5-9x^3-10x+8....i got -112...but i don't think its right

Answer 1

Not correct. Let's go through your work and find the mistake.

Answer 2

i used that table thing...and substituted the 4 into the g(x) so that the equation was g(4)=x^5-9x^3-10x+8...and then the table looked something like....

Answer 3

4^5-9*4^3-10*4+8
= 4^5- 9 *12 - 48
256-108 -48
148-48=100
