Answer:
I dont hell know
Step-by-step explanation:
Plug in the point
1 = 10 - 4(6)
1 = 10 - 24
1 = -14, false
Solution: B
Since <em>x</em> ² + 8<em>x</em> + 7 = (<em>x</em> + 7) (<em>x</em> + 1), we have for <em>x</em> ≠ -7,
<em>y</em> = (<em>x</em> + 7) / (<em>x</em> ² + 8<em>x</em> + 7) = 1/(<em>x</em> + 1)
so <em>y</em> is undefined at <em>x</em> = -1, indicating a vertical asymptote, and there is a hole/removable discontinuity at <em>x</em> = -7. Then the answer is D.
B, because -3^2 is not -9. -3*-3 = 9, square roots of negative numbers aren't possible, because no number squared can be equal to them. Instead, they are expressed in terms of "i", which is defined as
i^2 = -1
