Function of X

Rewrite the equation 2y = 3x + 4 as a function of x.

• y = (3/2)x + 4

• y = (2/3)x + 4

• y = (3/2)x + 2

• y = (3/2)x - 4

Write the equation 4y + 2x = 9 in the form of a function.

• y = (9 + 2x) / 4

• y = (9 + 2x) / 2

• y = (9 - 2x) / 2

• y = (9 - 2x) / 4

Write the equation 2y + 3x = 6 in the form of a function.

• f(x) = (6 - 3x)/2

• f(x) = (6 - 3y)/2

• f(x) = (6 - 2x)/3

Is this graph a function and how can you tell?

• Yes its a function cause it doesn't cross itself

• No it's not a function because it goes through the origin

• No it's not a function because the x value 4 has y values of  -2 & 2

• No it's not a function because the y value 4 has x values of  -2 & 2

Which of the following guarantees a table will not be a function?

• x value repeats

• y value repeats

• x value repeats and has different y values

• y value repeats and has different x values
