Without graphing, describe the end behavior of the graph of the function. f(x) = 1 - 2x2-x
1 answer:
Answer:
A
Step-by-step explanation:
When doing function behaviors it would be really helpful if you memorized the picture i've attached below
We can see that we have a negative leading coefficent and an odd degree which means that as x approaches -∞ it's positive and as x approaches ∞ it's negative
This means that the answer is A

We need to solve for x. Let's try problem b:
Let us first combine line terms. 3x and -x as well as 1 and -7 can be combined. Let's do that:
Since this is true, your answer would be:
All real numbers
------------------------------------------------------------------
Let's solve for problem c:
Let's isolate x, so subtract 1 from both sides:
Since x can't have a coefficient, divide both sides by 3:
So, only the value of 14 would make this equation true.
------------------------------------------------------------------
Let's try problem d:
Let's get our whole numbers on the right side. Add 1 to both sides:
Subtract 4x from the right side on both sides:
Since this is not true, your answer would be:
No solution
Answer:
<h2> - 320</h2>Step-by-step explanation:
a₁ = 10
a₂ = 6
d = a₂ - a₁ = 6 - 10 = -4
n = 16
a₁₆ = a₁ + (n-1)•d = 10 + (16-1)•(-4) = 10 - 60 = -50
