which statement is true about $f(x) = -6|x + 5| - 2?$○ the graph of $f(x)$ is a horizontal compression of the graph of the parent function.○ the graph of $f(x)$ is a horizontal stretch of the graph of the parent function.○ the graph of $f(x)$ opens upward.○ the graph of $f(x)$ opens to the right.
Answer
Explanation:
Step1: Recall parent absolute value function
The parent function is $g(x) = |x|$.
Step2: Analyze coefficient of absolute value term
For $f(x) = -6|x + 5| - 2$, the coefficient of $|x+5|$ is $-6$. Since $|-6| > 1$, this represents a vertical stretch, not horizontal. The negative sign means the graph opens downward.
Step3: Eliminate incorrect options
- Horizontal compression/stretch: The coefficient inside the absolute value is 1, so no horizontal transformation of stretch/compression. Eliminate first two options.
- Opens upward: The negative coefficient makes it open downward. Eliminate this option.
- Opens to the right: Absolute value functions of $x$ open up/down, not left/right. Eliminate this option. Wait, correction: Re-evaluate horizontal vs vertical. The coefficient outside the absolute value affects vertical scale. Since $|-6|>1$, it's a vertical stretch, but the options only have horizontal stretch/compression. Wait, no—wait, the horizontal transformation is from $|x|$ to $|x+5|$, which is a horizontal shift left 5, no stretch/compression. The coefficient -6 is vertical. But wait, none of the options mention vertical. Wait, no—wait, let's recheck: Wait, the options:
- Horizontal compression: No, horizontal stretch/compression is when you have $|kx|$ where $k≠1$. Here it's $|x+5|$, so $k=1$, no horizontal stretch/compression.
- Horizontal stretch: Same as above, no.
- Opens upward: No, negative coefficient means opens downward.
- Opens to the right: No, absolute value of $x$ opens up/down.
Wait, no—wait, I made a mistake. Wait, the question must have a correct option. Wait, no, wait: the coefficient outside is vertical. But the options for horizontal are wrong, but wait—wait, no, maybe I misread. Wait, $f(x) = -6|x+5| -2$. The parent is $|x|$. The $x+5$ is horizontal shift left 5. The -6 is vertical stretch by 6 and reflection over x-axis. The -2 is vertical shift down 2.
Wait, but the options: none say vertical stretch. Wait, the first two are horizontal. So they are wrong. Third says opens upward: wrong. Fourth says opens to right: wrong? That can't be. Wait, no—wait, maybe the question has a typo? No, wait, no—wait, no, I think I messed up. Wait, absolute value functions: if it's $|x|$, it opens up. If it's $|y|$, it opens right. But this is $f(x) = -6|x+5| -2$, which is a function of x, so it opens down. So all options? No, wait, no—wait, the first two options: horizontal compression/stretch. Wait, no, horizontal compression is when you have $|kx|$ with $|k|>1$, horizontal stretch when $0<|k|<1$. Here, inside the absolute value is $x+5$, which is $|1*x +5|$, so no horizontal stretch/compression. So first two are wrong. Third is wrong. Fourth is wrong? That can't be. Wait, no—wait, maybe I misread the function. Is it $f(x) = -6|x| +5 -2$? No, the function is $-6|x+5| -2$.
