A linear graph is a straight line graph. Thus, the graph does not represent a linear function.
A quadratic graph is either U-shaped or n-shaped. It is mostly in a parabolic form. Thus, the graph does not represent a quadratic function.
An exponential graph has asymptotic to the x-axis as x approaches negative infinity and the graph increases without bound as x approaches positive infinity. Also, the domain is all real numbers. Hence, the graph represents an exponential function.
CORRECT ANSWER: Exponential
