Evaluate the function f(x)=x^2+6x+2 at the given values of the independent variable and simplify.
a. f(-8)
b. f(x+2)
c. f(-x)
Answers
Answer:
a) 18
b)x^2+10x+18
c)x^2 -6x+2
Step-by-step explanation:
This is a case of plugging in the value into f(x).
a) f(-8)= -8^2 + 6(-8) +2
f(-8)= 64 + (-48) +2
f(-8)=64 + (-46)
f(-8)=18
b) f(x+2)= (x+2)^2+6(x+2)+2
So here I'll take a break to explain what's going on, because x+2 is a binomial meaning two terms and it is being squared I have to multiply the whole thing by itself. Meaning: (x+2) x (x+2), this is also known as foiling!! and for the next part its distributing 6 into x and 2.
f(x+2)= x^2+4x+4+6x+12+2
I'll reorder it
f(x+2)= x^2+4x+6x+12+2+4
f(x+2)= x^2+10x+18
c) f(-x)= -x^2+6(-x) +2
f(-x)= x^2 -6x+2

An art museum recently discovered that 12% of their paintings had been stolen and replaced with replicas. If a tourist observes 3 different paintings at random, what is the probability that exactly 2 are fakes? Write your answer as a decimal rounded to the nearest thousandth.
Answers
We will find that the probability that exactly one is original (or that exactly two are fakes) is 0.038
We know that 12% of the paintings are replicas.
Then if we see a random painting, the probability that it is a replica is 0.12
This means that the probability that a random painting is not a replica, is 1 - 0.12 = 0.88
Now we want to find the probability that exactly two out of 3 paintings are fake.
An easier thing to find is the probability that exactly one of the paintings is original (is exactly the same thing, just another viewpoint).
Let's assume the paintings are ordered, and the first one is the original one.
The probability of this will be:
P = 0.88*0.12*0.12
But we also have the case where the second one is the original, and the case where the third one is the original, so we have 3 possible permutations.
This means that the probability that exactly one is original (or that exactly two are fakes) is:
P = 3*(0.88*0.12*0.12) = 0.038

Given:
g(x)= 2x² - 3x + 19Evaluate each value:
A)
g(0) = 2(0)² - 3(0) + 19 = 19B)
g(-1) = 2(-1)² - 3(-1) + 19 = 2 + 3 + 19 = 24C)
g(3) = 2(3)² - 3(3) + 19 = 18 - 9 + 19 = 28D)
g(-x) = 2(-x)² - 3(-x) + 19 = 2x² + 3x + 19E)

The volume of a crate with length of x feet, width of 8 - x feet, and a height of x - 3 feet is given by V(x)=x(8−x)(x−3) find the maximum volume of the crate and the dimensions for this volume
Answers
Therefore, the dimensions for the maximum volume are x=8 and x=-3.
Now we can solve for the actual maximum volume:
V max =(8)(8)-(3)(8)=64.
The maximum volume is 64 cubic feet and the dimensions for this volume are 8x=-3
A polynomial is
if its only factors over the integers are 1 and itself.
Answers
Answer: Prime
A polynomial is prime if its only factors over the integers are 1 and itself.
==============================================================
Explanation:
Think of the idea of factoring whole numbers like factoring 36 into 6*6 which further breaks down into (2*3)*(2*3) = 2^2*3^2. This shows that 36 is composite and not prime.
Something like 7 is prime because the only factors are 1 and itself.
This idea extends into polynomials as well.
Something like x^2+4x+4 factors to (x+2)(x+2) which shows it is not prime. On the other hand, the polynomial x^2+3x+5 is prime over the integers because we cannot factor it like the previous example. The only factors here are 1 and itself.
Factoring is handy to help determine roots of a polynomial. However, other tricks could be used such as the quadratic formula or using numerical approximation techniques.

Here, we have [tex]f(x)=x^2.[/tex] We want to find f(g(x)). So, you should replace x in the function f(x) with the function g(x). [tex]g(x)=x-3.[/tex] So, f(g(x)) would equal [tex](x-3)^2[/tex], which equals [tex]x^2-6x+9[/tex].
