Notice how points T and Z are vertically aligned, or vertically lined up. This is where the graph fails the vertical line test.
The input x = 2 leads to the outputs y = 3 and y = 5 (which are the y coordinates of points Z and T in that order).
A function is only possible when any given input leads to <u>exactly one</u> output only. It would be like saying "the conversion function from Celsius to Fahrenheit has 0 degrees C convert to both 32 degrees F and 50 degrees F at the same time". But such a statement makes no sense and it's not useful. So this is one example of why having one output makes sense for a function.
In short, we need one output for any given input. But the input x = 2 leads to more than one output. That's why we don't have a function.
I don’t know I really don’t know, I am very confused ahhhhhhh!
Answer:
<h2>x=y+2/3</h2>
Step-by-step explanation:
y=3x-2
+2
y+2=3x
divide by 3
y+2/3=x
9/12 dividing both the numerator and the denominator by 3
9/3=3
12/3=4
this reduces down to 3/4
