Which model best fits the set of data shown on this graph?

a. quadratic model

b. quartic model

c. linear model

d. cubic model

C

Step-by-step explanation:

Quadratic model is shaped like a "U", or a parabola

Quartic model is shaped like a "W", highest degree is 4 (x^4).

Linear model is a line.

Cubic model is x^3, shaped like a curvy snake.

Looking at the graph, it clearly shows a line. So, linear model is the answer.

C is the correct answer.
