The Model Is Referred to as A:
A) Polynomial Model with One

The model $\mathrm { y } _ { \mathrm { i } } = \beta _ { 0 } + \beta _ { 1 } \mathrm { x } _ { i } + \beta _ { 2 } \mathrm { x } _ { i } ^ { 2 } + \beta _ { 3 } \mathrm { x } _ { i } ^ { 3 } + \ldots \ldots + \beta _ { y } \mathrm { x } _ { \mathrm { i } } ^ { \mathrm { p } } + \epsilon _ { 1 }$ is referred to as a:

A) polynomial model with one predictor variable.
B) polynomial model with p predictor variables.
C) polynomial model with (p + 1) predictor variables.
D) polynomial model with (x +1) predictor variables.
