If you apply the changes below to the linear parent function, f(x) = x, what is the equation fo the new function?
ad-work [718]

Answer:

D

Step-by-step explanation:

For a function in the form f(x) = x, we can say:

  • the function f(x) = ax is a vertical stretch if a>1 and compress if 0<a<1
  • the function -f(x) is the original, flipped over x-axis

<em>keeping the 2 rules in mind, we can say that</em>

<em>vertical stretch by a factor of 3 would make it f(x) = 3x</em>

<em>Then</em>

<em>flip over x-axis would make it f(x) = -3x</em>

<em />

answer choice D is right

3  {}^{4x  - 5}  = ( \frac{1}{27} ) {}^{2x + 10}  \\ note  \: \: that =  \\ ( \frac{1}{27} ) = ( \frac{1}{3 {}^{3} } ) = 3 {}^{ - 3}  \\  \\ 3 {}^{4x - 5}  = (3 {}^{ - 3} )  {}^{2x + 10}  \\ 3 {}^{4x + 5}  = 3 {}^{ - 3(2x + 10)}  \\ equal \:  \: bases =  > equal \: exponents

4x - 5 =  - 3(2x + 10) \\ 4x - 5 =  - 6x - 30 \\ 4x  + 6x =  - 30 + 5 \\ 10x =  - 25 \\ x =   - 2.5
