Question

Tell whether the following situation can be modeled by a linear function, an exponential function, a quadratic function or neither. The speed of a ball after a golfer hits it

Answer 1

Given the statement:

Speed of a ball after a golfer hits it

Let's determine whether the situation can be modeled using a linear, exponential or quadratic function.

After a golfer hits a ball, the ball starts from the initial position(rest), goes up and also comes down.

The movement of the ball will form a parabola.

A graph that has the shape of a parabola is the graph of a quadratic function.

The speed of ball after it is hit reduces with time.

A quadratic function has the form:

`f(x)=ax^2+bx+c`

Therefore, the speed of the ball after it is hit by a golfer can be modeled using a quadratic function

ANSWER:

Quadratic function
