One of the ways to graph this is to use plug in a few x-values and get an idea of the shape. Since the x values keep getting squared, there is an exponential increase on either side of the y-axis. You can see this by plugging in a few values:
When
x=0,f(x)=0
x=1,f(x)=1^2=1
x=2,f(x)=2^2=4
x=3,f(x)=3^2=9
x=4,f(x)=4^2=16
The same holds true for negative x-values to the left of the y-axis since a negative value squared is positive. For example,
x=−1,f(x)=(−1)2=1*−1=1
x=2,f(x)=(−2)2=−2*−2=4
The graph of f(x)=x^2 is called a "Parabola." It looks like this:
Answer:
R=-21
Step-by-step explanation:
R/5-(-4.2)=0
r+(4.2)*5=0
r+21=0
r=-21
This should be quite easy to explain. So the first thing you want to do is multiply them. This isn't to hard if you know your times tables. Don't worry about the decimal till the end.
15.37
× 5
---------
76.85
15.37 times 5 is 76.85
Now on to the decimal. All you need to do is move it two times to the left. You see how it's in between the 5 and 3? The same goes for your answer. So it is 76.85
I hope this helped!! ^^ I can make this a little more easier to explain if you want me to just in case, ok?
A: 600 Centimeters
Reason: 60c x 10 days = 600c
B:
1800 centimeters
Reason 60c x 30 days = 1800c
C:
30 centimeters
Reason: 60c x .5 = 30c
.5=12 hours
1.5=36 hours
Parallel line means the same slope
（8-1）/(-17-a)=(1-5)/(a+2)
so a is 18
