Answer:

The second function represents an even function; g(x)=2x^{2} +1

Step-by-step explanation:

A function f(x) is said to be even if f(x) = f(-x). All we need to do is replace x with -x in each equation, simplify it and assess whether the equation remains unchanged. If  the equation is identical to the original one then it is said to be even. Another good example of an even function is the cosine function. Moreover, even functions have y-axis symmetry

Answer:

Choice B is correct answer.

Step-by-step explanation:

We have given four functions.

We have to choose the even function.

A function is even when

       f(x) = f(-x)

A.   g(x) = (x-1)²+1

   g(-x) = (-x-1)²+1

   g(-x) ≠ g(x)

B.  g(x) = 2x²+1

 g(-x) = 2(-x)²+1

   g(-x) =  2x²+1

hence, g(x) =  g(-x)

C.   g(x) = 4x+2

g(-x) = 4(-x)+2

g(-x) =  -4x+2

hence,  g(-x) ≠ g(x)

D.    g(x) =2x

  g(-x) = 2(-x)

  g(-x) = -2x

hence,  g(-x) ≠ g(x)

Choice B is correct answer.

The youth group is going on a trip to the state fair. The trip costs $63. Included in that price is $13 for a concert ticket and
forsale [732]

Ok,

The total is 63$:

= 63

It shows us one of the numbers for the equation, 13

+ 13 = 63

Two passes together plus the thirteen equals the total of 63$

the price of the pass is unknown, so we can use a variable to figure it out:

2x + 13 = 63

Now we solve

First subtract 13 from both sides:

2x + 13 - 13 = 63 - 13

Then divide both sides by 2:

2x ÷ 2 = 50 ÷ 2

Now we get our answer:

x = 25

For question 7, if we add all votes for tiger and eagle, we get

tiger = 14 + 13 + 8 + 5 = 40
eagle = 6 + 7 + 12 + 15 = 40

so choices A and B are wrong.
C is also wrong because fifth and sixth grade votes for eagle are 6 + 7 = 13 and the 5th and 6th grade votes for tiger are 14 + 13 = 27. clearly 5th + 6th like tiger more.

D is the answer for question 7

question 8

rolling a cube does not affect the other cube so it is all independent probability.
cube: 1 2 3 4 5 6
3 even numbers and 3 odd numbers

so probability of rolling an even number is

1/6 + 1/6 + 1/6 = 3/6 = 1/2

multiplying by total number of rolls, she will get even numberss

300 * 1/2 = 150

about 150 time.
so half of the time, Cassie will roll and even number about half the number of rolls. never exactly since this is all probability. more likely for it to be around 150 times than exactly 150 time.

choice C is answer for question 8
