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)?

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

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

For the proportion, find the unknown number n. 9.6/16 = n/3.2​
larisa [96]

Answer:

n = 1.92

Step-by-step explanation:

Multiply both sides of the equation by 3.2

3.2*\frac{2}{3.2} =3.2*\frac{9.6}{16}

Simplify both sides of the equation.

n = 1.92

<em>good luck, i hope this helps :)</em>
