if f(x) = x3  + 4x and g(x) = -2x + 1, then f(g(3))= ?

-3

Step-by-step explanation:

First find g(3).

So g(3)= -2(3)+1 so g(3)= -5

now plug this value into f(x).

f(-5)= (-5)3 +4(3) = -15+12 = -3

- 145

Step-by-step explanation:

To evaluate f(g(3)), evaluate g(3) then substitute the result into f(x)

g(3) = - 2(3) + 1 = - 6 + 1 = - 5, then

f(- 5) = (- 5)³ + 4(- 5) = - 125 - 20 = - 145

to determine the unit cost your would divide the total cost by the number sold.

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
