What is a function? I want the actual definition pleaseeee
Every input has exactly one output.

(0,25)
Explain how to do the Vertical Line Test and what's it's do.
The vertical line test is using a vertical line (like a pencil/pen/finger) and running it over a graph to check if it's a function. If the vertical line touches the graph twice at the same time at any point, the graph is NOT a function.

(0,-22.5)
Say I graphed y = -5x + 30
Is the point (5, -55) on the line?
No because when I plug in 5 for x, y = 5 not -55
Is this table a function?

No because one input cannot have 2 outputs, input = 50

-2
Why is this graph not a function. Use input 4 in your explanation. (I have to like your explanation) :)

Because input 4 has 2 outputs (-2 & 2), making it not a function.
“Number of hours studied → test score”
Is this guaranteed a function? Explain why.
Not necessarily. The same number of hours studied could lead to different test scores.
