x:4 5 7 10

Question

y:4 5 0 8 1
is this a function or not a function.

Answer 1

This set of data is not a function because the input value of 7 in x corresponds to two different output values in y (0 and 8). In order for a set of data to be considered a function, each input value must correspond to only one unique output value.

Answer 2

what about 4x+53=y

Answer 3

The equation 4x + 53 = y represents a function because for each input value of x, there is only one corresponding output value of y. This is a linear function where the output value is dependent on the input value through a single equation.

Answer 4

and what about y=8x^2

Answer 5

The equation y = 8x^2 represents a function because for each input value of x, there is only one corresponding output value of y. In this case, the output value is calculated as 8 times the square of the input value x, which satisfies the definition of a function.
