-4n + 9 = -4n + 9
Answer:
Yes, f(x) =
is a constant function.
Step-by-step explanation:
A function is defined to be a relation from 1 set of numbers to another set of numbers.
The main condition for a relation to be a function is that for every number in the domain there should be a <u>unique image</u>
Here the given function is f(x) = ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
This function is a constant function and gives the value 0.75 for all values of x.
Hence the graph would be a straight line parallel to the x-axis passing through y = 0.75.
Hence the f(x) = 0.75 is a function.
Answer:
The standard form of line is
![-3x+y=-2](https://tex.z-dn.net/?f=-3x%2By%3D-2)
Step-by-step explanation:
we are given a line
slope=3
so,
![m=3](https://tex.z-dn.net/?f=m%3D3)
y-intercept of -2
so,
![b=-2](https://tex.z-dn.net/?f=b%3D-2)
now, we can use slope-intercept form of line
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
now, we can plug values
![y=3x-2](https://tex.z-dn.net/?f=y%3D3x-2)
we can write it in standard form of line
![ax+by=c](https://tex.z-dn.net/?f=ax%2Bby%3Dc)
![y=3x-2](https://tex.z-dn.net/?f=y%3D3x-2)
we can subtract both sides by 3x
![y-3x=3x-2-3x](https://tex.z-dn.net/?f=y-3x%3D3x-2-3x)
![y-3x=-2](https://tex.z-dn.net/?f=y-3x%3D-2)
![-3x+y=-2](https://tex.z-dn.net/?f=-3x%2By%3D-2)
So, the standard form of line is
![-3x+y=-2](https://tex.z-dn.net/?f=-3x%2By%3D-2)
