Select all the correct answers. Which equations represent functions?
2 answers:
Hello.
Functions are a relationship between two variables such that for every value of x there is one value of y. The easiest way to see if a given equation is a function is by graphing it.
I will post photos of each graph (in order).
So therefore, the equations that represent functions are A and D.
Answer:
option A and D
Step-by-step explanation:
Select the equation that represent function.
A relation is a function that relates the variables x and y that is input and output.
A relation is a function that satisfies vertical line test.
x= some number is a vertical line that is not a function.
y= some number is a horizontal line that passes vertical line test, so it is a function.
a. is a linear equation. It is a function.
b. . It is a vertical line, so it is not a function.
c. It is a vertical line, so it is not a function.
d. It is a horizontal line, so it is a function.
e. It is a vertical line, so it is not a function.
