Which of the following is a linear function? y = x3 + 1 x = y − 4 y = 8x2 y = 1/5x

Step-by-step explanation:

As written, they all are linear functions.

If we assume that x3 is supposed to be interpreted as x³ = x^3, and that x2 is supposed to be x² = x^2, then the equations containing those terms are not linear equations.

The equation y = 1/5x is usually interpreted to mean y = (1/5)x. If it is intended to be y = 1/(5x), then it is not a linear function either.

___

A linear function is a sum of terms that are either constant or containing a single variable to the first power.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
