Because x is negative the domain of the function is all negative real numbers.
Set the radical greater than or equal to 0:
-x >= 0
Turn x positive by multiplying both sides by -1. When you multiply an inequality by -1 you need to reverse the inequality sign:
X <= 0
Domain is all real numbers below 0 so all negative real numbers.
Answer:
<em>19</em>
Step-by-step explanation:
has a factor 
and
when divided by 
, remainder is 20.
To find:Remainder when divided by (x-1) ?
Solution:
is a factor
when we put this value of x to the function, it will become 0.
i.e.
Remainder is 20 when f(x) is divided by
i.e.
Solving (1) and (2), Multiply equation (1) by 2 and adding to (2):
By equation (1):
So, the equation becomes:
So, when divided by (x-1), remainder will be <em>19</em>.
I think the answer is 1.97 hope it helps you
I think you can find it graphically by points through a table you create like:
let x = 0, and find the value of y
for example for the first equation when we let x = 0 you find y = 6 and be in the form of (0,6) then draw them or you can let x = -2 or -3 , etc as you like
to be more accurate you can find 3 pionts and start graphing them
these two equations are straight lines and they will intersect in a point
