F1 Intro to Functions Practice Quiz
The range is a list of all possible outputs.  The outputs areusually represented by "y", are usually the dependentevent, and are usually the effect.
The domain is a list of all possible inputs.  The inputs areusually represented by "x", are usually the independentevent, and are usually the cause.

1)  Is (2, 14) a solution

of y = 5x + 4?

Replace x with 2 and y with 14 and see if it is true.
y = 5x + 4  becomes 4 = 5(2) + 4.  Is it true?
yes

no

2)  Is (0, 4) a solution

of y = 5x + 4?

yes

no

3)  Is (2, 3) a solution

of y = 3x - 4?

yes

no
