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)?
melamori03 [73]
\bf ~~~~~~~~~~~~\textit{function transformations}&#10;\\\\\\&#10;% templates&#10;f(x)=  A(  Bx+  C)+  D&#10;\\\\&#10;~~~~y=  A(  Bx+  C)+  D&#10;\\\\&#10;f(x)=  A\sqrt{  Bx+  C}+  D&#10;\\\\&#10;f(x)=  A(\mathbb{R})^{  Bx+  C}+  D&#10;\\\\&#10;f(x)=  A sin\left( B x+  C  \right)+  D&#10;\\\\&#10;--------------------

\bf \bullet \textit{ stretches or shrinks horizontally by  }   A\cdot   B\\\\&#10;\bullet \textit{ flips it upside-down if }  A\textit{ is negative}\\&#10;~~~~~~\textit{reflection over the x-axis}&#10;\\\\&#10;\bullet \textit{ flips it sideways if }  B\textit{ is negative}\\&#10;~~~~~~\textit{reflection over the y-axis}&#10;\\\\&#10;\bullet \textit{ horizontal shift by }\frac{  C}{  B}\\&#10;~~~~~~if\ \frac{  C}{  B}\textit{ is negative, to the right}

\bf ~~~~~~if\ \frac{  C}{  B}\textit{ is positive, to the left}\\\\&#10;\bullet \textit{ vertical shift by }  D\\&#10;~~~~~~if\   D\textit{ is negative, downwards}\\\\&#10;~~~~~~if\   D\textit{ is positive, upwards}\\\\&#10;\bullet \textit{ period of }\frac{2\pi }{  B}

with that template in mind

\bf f(x)=2^x\qquad &#10;\begin{cases}&#10;g(x)=f(x+k)&k=5\\&#10;\qquad\quad f(x+5)\\&#10;\qquad \quad 2^{x+5}&#10;\end{cases}

notice, in g(x)

B = 1, no change from parent

C= +2

What is the equation 3n+2=15
scoray [572]

Solution for 3n-2=15+3n equation:

Simplifying

3n + -2 = 15 + 3n

Reorder the terms:

-2 + 3n = 15 + 3n

Add '-3n' to each side of the equation.

-2 + 3n + -3n = 15 + 3n + -3n

Combine like terms: 3n + -3n = 0

-2 + 0 = 15 + 3n + -3n

-2 = 15 + 3n + -3n

Combine like terms: 3n + -3n = 0

-2 = 15 + 0

-2 = 15

Solving

-2 = 15

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.
