If a polynomial is divisible by
, then
is a root of this polynomial.
Here (x-a) is equal to x+2:
So -2 is a root of the polynomial. That means <span>x³-6x²+kx+10</span>=0 for x=-2. Now substitute -2 for x in the equation and solve for k:
Answer:20- 2 x (5 +2)
Step-by-step explanation:
20 - 2 x (5 + 2)
20 - 2 x (7)
20 - 14

Answer:
(-2,1)
Step-by-step explanation:
So we are given f(-3)=1 since the point (-3,1) is on f(x).
We want to use this point to find a point on f(x-1).
Now,
f(-3)=1
and we want
f(x-1)=1
What would x need to be such that x-1 is -3.
x-1=-3
Add 1 on both sides:
x=-3+1
x=-2
x would need to be -2 in f(x-1)=1 in order to use that f(-3)=1.
So (-2,1) is the point for the function f(x-1) that corresponds to the point (-3,1) for f(x).
I know that f(x-1) would only be effecting our input because x-1 is the input.
Answer:
Step-by-step explanation:
Let the exponential function be 
.
When x=0, 
The function now becomes 
When x=1, f(1)=-5
This implies that:
Therefore the equation for the exponential function represented in the table below is
