Based on the polynomial remainder theorem, what is the value of the function when x = 4? f(x)=x^4−2x^3+5x^2−20x−4 what does f(4) =

f(4) = 124

Step-by-step explanation:

The polynomial remainder theorem says the value of the function is the remainder when when the function is divided.

Using synthetic division.  

f(4)=

              1      -2       5       -20         -4

4                    4       8         52        128

            1      2        13          32       124

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
