Answer:4,200
Step-by-step explanation:
1. A relation is a set from x to a set y is called a function if each element of c is related to exactly one element in y. That is,given an element c in c, there is only one element in y that x is related to.
2. You can set up the relation as a table of ordered pairs. Then, text to see if each element in the domain is matched with exactly one element in the range . if so you have a function
3. The domain is the set of all possible x-values which will make the function "work" and will output real y- values .When finding the domain , remember :the denominator (bottom) of a fraction cannot be zero .

Answer:
F(x) = 1/x^2
Step-by-step explanation:
F(x) = 1/x^2 is
y = 1/x^2
graph goes up to 10 each side
plug in 1,2,3,4,5,6,7,8,9,10 for x and see what y looks like
when x is 1,2,3,4,5,6,7,8,9,10
y is 1,1/4,1/9,etc
"Two significant figures" means that a digit after the second one could actually be anything ... it wasn't measured. 'X' could be anything from 230 to 239. 'Y' could be anything from 400 to 409.
The greatest possible value of that fraction is. (239)/(409 squared) .
Answer:
![y = \frac{3}{4}x - 2](https://tex.z-dn.net/?f=%20y%20%3D%20%5Cfrac%7B3%7D%7B4%7Dx%20-%202%20)
Step-by-step explanation:
Equation of a line is given as ![y = mx + b](https://tex.z-dn.net/?f=%20y%20%3D%20mx%20%2B%20b%20)
Where,
m = slope of the line = ![\frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20)
b = y-intercept, which is the value at the point where the line intercepts the y-axis. At this point, x = 0.
Let's find m and b to derive the equation for the line.
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20)
Use the coordinate pair of any two points on the line. Let's use the following,
=> on the line, when x = 0, y = -2
=> on the line, when x = 4, y = 1
Plug in the values and solve for m
![m = \frac{1 - (-2)}{4 - 0}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7B1%20-%20%28-2%29%7D%7B4%20-%200%7D%20)
![m = \frac{1 + 2}{4}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7B1%20%2B%202%7D%7B4%7D%20)
![m = \frac{3}{4}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20)
b = -2 (the line intercepts the y-axis at this point)
Our equation would be =>
![y = mx + b](https://tex.z-dn.net/?f=%20y%20%3D%20mx%20%2B%20b%20)
![y = \frac{3}{4}x + (-2)](https://tex.z-dn.net/?f=%20y%20%3D%20%5Cfrac%7B3%7D%7B4%7Dx%20%2B%20%28-2%29%20)
![y = \frac{3}{4}x - 2](https://tex.z-dn.net/?f=%20y%20%3D%20%5Cfrac%7B3%7D%7B4%7Dx%20-%202%20)
