Question

Help! p(x) = 4x^4 - 10x^3 + 8x - 1
x = 8

Answer 1

p(8) = 11,327

Explanation:

Hey there!

In order to find the answer, all we need to do is subtitute the x values for 8

After substituting, the equation will look like this:

`p(8)=4(8)^4-10(8)^3+8(8)-1`

Now we simplify

8 to the power of four is 4096 and when you multiply that by 4, you get 16384

8 to the power of 3 is 512 and when you multiply that by -10, you get -5120

8 times 8 is 64

And then there is -1

Now all we have to do is combine all the answers together for one final answer

16384-5120+64-1 is equal to 11327

So the output of this function when you input 8 is 11,327
