Your friend hands you a graph of the engine power statistics of a race car. He says, “I know this graph is f(x) = –3(x + 4)^6 – 8 but I can’t remember how it is related to the graph of x^4.” Explain to your friend how the graph f(x) is a translation of the graph x^4. I get translations, but I can't seem to identify this one.
i hope there is a typo there
\[ f(x) = –3(x + 4)^6 – 8\] should maybe be \[ f(x) = –3(x + 4)^4 – 8\]
it is shifted a few ways
4 units to the left flipped about the \(x\) axis because of the \(-3\) then down \(8\) units because of the \(-8\) also narrower because of the \(x^6\)
it is the minus sign that flips it over the \(x\) axis
compare say \(y=x^2\) to \(y=-x^2\)
and \(x^6\) is narrow than \(x^4\) because raising a number to the power of 6 makes it a lot bigger than raising it to the power of 4 (assuming it is larger than 1)
yes
i mean yes the \(x+4\) shifts it 4 units left
sure what is the other one ?
they really stretch to make these word problem, don't they? "break even" they tell you just means \(p(x)=0\) so you have to find the zeros of this thing your first answer is correct. lets find the zeros
yes stay graphical the zeros are not rational
well really it would not have domain \(\mathbb{R}\) but rather \((0,\infty)\) since you do not make a negative amount of cans
yes
