Answer:
3. increasing
4. decreasing
Step-by-step explanation:
well for graph 3 the values are increasing
and for graph 4 the values are decreasing
Given a1 = 90
Common difference = adding
90 + 9 = 99, second term
99 + 9 = 108, third term
And keep doing that
You would get
90, 99, 108, 117, 126, 135
When you want to write a polynomial, you should write the term with the highest degree first.
Here, it should go like this: d^3 + d^2 - d + 3
This means that the term which should be written first is the cubic term.
Answer:
x^2 -2x+1
Step-by-step explanation:
(x - 1 )(x - 1)
FOIL
first: x*x = x^2
Outer: -1x
inner: -1x
Last: -1*-1 = 1
Add these together
x^2 -1x-1x+1
x^2 -2x+1
