Given f(x) = x^3 + kx + 2, and x + 1 is a factor of f(x), then what is the value of <br> k?
Aleks [24]

Answer:

k = 1

Step-by-step explanation:

Given that,

f(x) = x^3 +kx + 2

If (x+1) is a factor of (x), we need to find the value of k.

Using remainder theorem to find it.

Put (x+1) = 0

x = -1

Put x = -1 in equation below.

x^3 + kx + 2=0\\\\(-1)^3+k(-1)+2=0\\\\-1-k+2=0\\\\1-k=0\\\\k=1

So, the value of k is 1.

________________________________________________
The pay, "p" , is a function of the hours worked.

When h = 2,  (h = number of hours);  

         the pay, "p" ,  is equal to " 7.50 * 2 "  = 15.00 dollars" ; as shown on table.

When h  = 4  ;  p = " 7.50 * 4 = 30.00 dollars" ; as shown on table .

When h = 6 ; p = " 7.50 * 6 = 45.00 dollars" ; as shown on table.

When h = 8 ; p = " 7.50 * 8 = 60.00 dollars" ; as shown on table.
