question

What type of function does this graph show?

linear

quadratic

exponential

key idea


linear	quadratic	exponential

solution

The graph of a linear function is a straight line. The given graph shows a straight line, so it is linear function.

The graph of a quadratic function is a parabola that opens up or down. The given graph is not a parabola, so it is not quadratic.

The graph of an exponential function has one horizontal asymptote. The given graph does not approach a horizontal asymptote, so it is not exponential.

In summary, the given graph shows a linear function.
