How do we solve input and output of a graph

Answer and Step-by-step explanation:

input and output are essentially variables

input is the variables in the equation that you put into the number

the output is the answer you get once you put in the input

(I hope that helps, usually i am good at explaining using numbers than in words)

ex#1:  10=output     input=x

f(x)=10, find x when

f(x)=2x+6

so when you are solving the input, you just are solving for for a variable (in this case it's x)

so... 10=2x+6  

x=2

But if you are looking for the outputs, you just plug in the variable's value and solve in the equation.

ex#2: Find when f(2)

So what you do to find the output(answer), you just plug in the number that is in the f(x), in this case it's 2

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

boxplot e is the answer
