Is the function linear or exponential? Explain the reasoning.
The function is exponential because there is a constant rate of change: for every increase in z, the y-value increases by 1.3
The function is exponential because there is a proportional rate of change; for every increase in z, the y-value increases by a factor of 1.3.
The function is linear because there is a constant rate of change; for every increase in z, the y-value increases by 1.3.
The function is linear because there is a proportional rate of change: for every increase in z, the y-value increases by a factor of 1.3.
