To stretch it vertically, you'll need a coefficient greater than 1 in front of the x. If you want to flip the graph over the x axis that coefficient needs to be negative. So it can only be D

The function rule of a certain function is y = -3x + 1. If the input is 7, what is the output?
tekilochka [14]

Answer:

-20

Step-by-step explanation:

y = -3x+1

if the input is 7, it means x=7 so substitute in the equation

y= -3*7+1 = -21+1= -20 which is the output

What function represents the pattern shown in the table?
Pavlova-9 [17]

Given:

The table of values of an exponential function.

To find:

The function for the given table of values.

Solution:

The general exponential function is:

y=ab^x        ...(i)

Where, a is the initial value and b is growth factor.

From the given table it is clear that the function passes through the points (1,9) and (2,36). It means the function must be true for these two points.

9=ab^1        ...(ii)

36=ab^2       ...(iii)

On dividing (iii) by (ii), we get

\dfrac{36}{9}=\dfrac{ab^2}{ab}  

4=b  

Putting b=4 in (ii), we get

9=a(4)^1

\dfrac{9}{4}=a

Putting a=\dfrac{9}{4},b=4 in (i), we get

y=\dfrac{9}{4}(4)^x

y=9(4)^{x-1}

The function notation with variable n is:

f(n)=9(4)^{n-1}

Therefore, the correct option is D.

I really need help I’m very confused
Vaselesa [24]

Answer:

10: -11n^5

12: 6k^2 -6k+7

Step-by-step explanation:

Ok so what your gonna do is add or subtract the ones with the same exponent.

so -15+4= -11 since they are both n^5 you can add them so your answer is:

-11n^2

now you have 8k^2-k-5k+7-2k. so you are gonna rearrange them so the same exponents are together.(keep the sign in front in front, if no sign it is positive)

8k^2-2k^2-5k-k+7

add like exponents

6k^2-6k+7
