Question

Which graphs below represent an exponential function? Select all that apply.

Answer 1

Answer with explanation:

We know that the graph of an exponential function is:

• A non-linear curve which is either continuously increasing i.e. it represents a exponential growth function

• or a non-linear curve which is continuously decreasing represent a exponential decay function.

• ( A linear function has a graph as a straight line such that the line could be constant or strictly increasing or decreasing.

• Also, the graph of a quadratic function is a parabola which may open upward or downward)

Answer 2

The two graphs in the second picture are the graphs of exponential functions. You can detect it from the L shaped graphs.

The very first graph represents a linear function. A straight line always represents a linear function. In a Linear function, the change in the values of y is constant throughout in relative to change in x values.

The final graph represents a quadratic function rising on both ends.

Therefore, option b and c are the correct answers
