Answer:

Step-by-step explanation:

To find the mean, you have to add all the numbers together and then divide it by the amount of numbers that you added together.

For example, 23 + 18 + 24 + 15 + 25 = 105

105 ÷5 = 21

Evaluate the functionf(-x) = f(x) plug in the points (2,1) then solve

jarptica [38.1K]

Problem

evaluate the function

f(-x) = f(x)

plug in the points (2,1) then solve

Solution

For this case we can conclude that:

f(2) =1

So then we satisfy that:

f(-2) =1

The function f(x)=2^x and g(x)=f(x+k). If k=-5,what can be concluded about the graph of g(x)?

$\bf ~~~~~~~~~~~~\textit{function transformations}

f(x)= A( Bx+ C)+ D
\\\\
~~~~y= A( Bx+ C)+ D
\\\\
f(x)= A\sqrt{ Bx+ C}+ D
\\\\
f(x)= A(\mathbb{R})^{ Bx+ C}+ D
\\\\
f(x)= A sin\left( B x+ C \right)+ D

$\bf ~~~~~~if\ \frac{ C}{ B}\textit{ is positive, to the left}\\\\

with that template in mind

$\bf f(x)=2^x\qquad 
\begin{cases}
g(x)=f(x+k)&k=5\\
\qquad\quad f(x+5)\\
\qquad \quad 2^{x+5}
\end{cases}$

notice, in g(x)

B = 1, no change from parent

C= +2
