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:
Graph the equation in a graphing calculator or in the table in a regular calculator and look for the zero on the x axis and the y axis
Answer:
Use this formula for these kinda things.
Step-by-step explanation:
Remember The z is the hypathonous, it means the biggest side.
![{a}^{2} + {b}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20%20%7Bc%7D%5E%7B2%7D%20)
where Z is going to be C
put this all together
![{7}^{2} + {18}^{2} = {z}^{2}](https://tex.z-dn.net/?f=%20%7B7%7D%5E%7B2%7D%20%20%2B%20%20%7B18%7D%5E%7B2%7D%20%20%3D%20%20%7Bz%7D%5E%7B2%7D%20%20)
put it into calculator, means 373=
![{z}^{2}](https://tex.z-dn.net/?f=%20%7Bz%7D%5E%7B2%7D%20)
therfore take the square root, it will be
![z = \sqrt{373}](https://tex.z-dn.net/?f=z%20%3D%20%20%5Csqrt%7B373%7D%20)
which it will be 19.31
Answer:
x = 1.24
Step-by-step explanation:
In order to get that x down from its current position of exponential, you need to take either the log or the natural log of both sides. The power rule tells us that we can then pull the exponent down in front. So let's take the natural log of both sides:
![ln(83)=ln(35)^x](https://tex.z-dn.net/?f=ln%2883%29%3Dln%2835%29%5Ex)
We can bring the x down in front to give us:
ln(83) = x ln(35)
The right side of this is "stuck" together by multiplication, so we can undo that multilication by division of the ln(35). That leaves us with just x on the right:
![\frac{ln(83)}{ln(35)}=x](https://tex.z-dn.net/?f=%5Cfrac%7Bln%2883%29%7D%7Bln%2835%29%7D%3Dx)
Do this on your calculator and find that x = 1.24
Hello! I believe the answer is 27.71.
I hope this helps!
