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 is curved, so it is not linear.

The graph of a quadratic function is a parabola that opens up or down. The given graph shows a parabola that opens downwards, so it is 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 quadratic function.
