Graph the function f(x) = - squared x + 2

MariettaO [177]3 years ago
5 0

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:

How many meters are there in 33 km?
s2008m [1.1K]
1000 meters make 1km. So let's compare that with the question.
1000m=1km
Y=33km
I represented the unknown with Y. Next, you have to cross and multiply. 33 will multiply 1,000 to give 33,000. And Y will multiply 1 to give Y. That will be;
Y=33,000m
33km makes 33,000m.
Hope that helped. Have a nice day

Which electron configuration represents the electrons of a sulfur atom in an excited state? Choice number 2 (1) 2-6-6 (3) 2-8-4
Archy [21]

Answer:

<em>(3) 2-8-4</em>

<em></em>

Step-by-step explanation:

Sulphur has an atomic number of 16

sulphur can exist in 3 different excited states of +2, +4 and +6

electronic configuration of sulphur is 2,8,6

when excited, <em>it loses 2 electrons to enter the +2 state</em>

in the +2 state, the electronic configuration will be <em>2,8,4</em>
