Looking at how the image shrinked from the original, you can assume that the scale would be a fraction. Since they remained negative, then the fraction wouldn't contain a negative. Therefore the answer would be C.

The function f(x)=(x-1)^2-4 is not one-to-one. If you restrict the domain for f(x) to x(less than or equal to symbol)1, what is

olasank [31]

$\text{We have been given the function }\\
f(x)=(x-1)^2-4\\
\text{Let f(x)=y}\\
y=(x-1)^2-4\\
\text{Swap x and y, we get}\\
\\
x=(y-1)^2-4\\
\text{Now we solve for y}\\
(y-1)^2=x+4\\
\\
y-1=\pm \sqrt{x+4}\\
\\
y=1\pm \sqrt{x+4}\\
\\
f^{-1}(x)=1\pm \sqrt{x+4}\\$

$x+4\geq 0\\
x\geq -4\\
\text{Thus, the domain is given by}\\
x\in [-4,\infty )$

<u>Step-by-step explanation:</u>

<u>Let's simplify the inequality first.</u>

=> -4x < 8
=> -4x/4 < 8/4
=> -x < 2
=> x < -2

Hence, <u>the solution of the inequality is</u><u> x < -2.</u>
