The parabola y = x² - 4 opens:
A.) up
B.) down
C.) right
D.) left
1 answer:
Answer:
Up
Step-by-step explanation:
Here the easy rules to remember the orientation of the parabolas are
a) If x is squared it opens up or down. And its coefficient of {
Hence in our equation of parabola
x is squared and its coefficient is positive , hence it opens up towards positive y axis.

its A. B. C. D. E.
Step-by-step explanation:
all of it are correct
That ^^^ is wrong
what you have to do is multiply the circumference by pi to get your answer
Your answer would be y=4x+17
That’s a good deal if i do say so myself.
Y=21n(x2+2)y=21n(x2+2)
21n(x2+2)(y-1)=0
n=0, x=i/2-i/2, y=1
