Question

the graph shows the birds height during 30 seconds. what is the y - intercept? what does this mean about the birds height at the beginning of the observation?
the y - intercept is □. (type an integer or a decimal.)

Explanation:

Step1: Recall the definition of y - intercept

The y - intercept is the value of the function when \(x = 0\). In the context of the graph (where \(x\) represents time and \(y\) represents height), we look at the value of \(y\) (height) when \(x=0\) (beginning of the observation).

Step2: Locate \(x = 0\) on the graph

Looking at the graph, when \(x = 0\) (time = 0 seconds), the value of \(y\) (height) is \(10\).

Answer:

\(10\)
