Answer:-55/4

Step-by-step explanation:

-880,-220,-55,...

First term=a=-880

Common ratio=r=-220/-880=1/4

Using the formula

Tn=a x r^(n-1)

T4=-880 x (1/4)^(4-1)

T4=-880 x (1/4)^3

T4=-880 x 1/4 x 1/4 x 1/4

T4=-880 x 1/64

T4=-880/64

T4=-55/4

Which of the following describes the transformations of g (x) = negative (2) Superscript x + 4 Baseline minus 2 from the parent
o-na [289]

Answer: First option.

Step-by-step explanation:

Below are some transformations for a function f(x):

1. If f(x)+k, the function is shifted "k" units up.

2 If f(x)-k, the function is shifted "k" units down.

3. If f(x-k), the function is shifted "k" units right.

4. If f(x+k), the function is shifted "k" units left.

5. If -f(x), the function is reflected over the x-axis.

6. If f(-x), the function is reflected over the y-axis.

Then, given the parent function f(x):

f(x)=2^x

And knowing that the the other function is:

g(x)=-2^{(x+4)}-2

You can identify that the function g(x) is obtained by:

- Shifting the function f(x) 4 units left.

-  Reflecting the function  f(x) 4 over the x-axis.

- Shifting the function f(x) 2 units down.

Please some help for question 1
o-na [289]

Answer:

f (3) is equal to 31

Step-by-step explanation:

f (3) means that x is equal to 3 [hence f (x) ---> f (3)]

Plugin 3 into all the x values to solve:

4(3)^2 - 2(3) + 1

4(9) - 6 + 1

36 - 6 + 1

30 + 1

31

f (3) is equal to 31
