Step-by-step explanation:
The standard equation is 4p(x-h) = (y-k)^2 where |p| = focal distance |4p| = focal width.
<span>x=-1/8y^2
-8x=y^2
4*(-2)(x-0) =( y-0)^2
p = -2, h=0, k=0</span><span>
focal width = |4*(-2)| = 8
The answer to your question is that the length of the focal width is equal to 8.</span>
Answer:
b
Step-by-step explanation:
1. the function will approach negative infinity as x approaches neg/pos infinity because -x^4 (highest power) will result in both ends pointing down. this rules out a and d.
2. skip the Maxima/minima part
3. to test for zeroes, list all possible zeroes using rational zero theorem. then use synthetic division to test out the differing zeroes between b and c.
we find -5 leaves us with remainder of 0, so it is a zero where as -7 leaves us with some remainder that isn't 0, so it is not a zero.
the only option with the function approaching negative infinity with a zero at -5 is b
