Answer:
(x-4) is not a factor of f(x)=x³-2x²+5x+1
Step-by-step explanation:
Uding the remainder theorem,(x-4) is a factor if the remainder is 0
Plug in x=4
(4)³-2(4)²+5(4)+1
64-32+20+1
64-53
11
ANSWER

EXPLANATION
The given expression is

We regroup the numerical parts to get;

Now let us simplify the negative numbers.

We now subtract 19 from 42 to get;

We can't simplify further
Hence the simplest form is:

Is it 4 times x or 4 to the power of x, if the first one then, 8x-24x. if the second then 8^-6x
Answer:
i think its A
Step-by-step explanation:
divide both sides by -2 which makes the y int -3 and A has a negative slope
