Step-by-step explanation:
Answer:
y=500+75x
Step-by-step
because it says plus a charge so you add
Answer:
k = -2
Step-by-step explanation:
If 
Then
So
From this follows k = -2
Answer:
y = -1/4 -5
Step-by-step explanation:
Any equation will be parallel to your base equation as long as the y intercept is different. To write a parallel equation, you just have to change the y intercept.
For example, I changed it from 2 to negative 5.
Answer:
Invertible functions
Step-by-step explanation:
An inverse of a function is one that reverses the operation of the function such that the result of the function on a variable, is reversed back to the initial variable
Therefore, when we have the the result of the function, f on x as y given as follows;
f(x) = y
The inverse of the function, g on the result, y gives the initial variable, x as follows;
g(y) = x
Example of invertible functions includes;
f(x) = x²
An example of a non-invertible function includes;
f(x) = 2·x².
