Question

1. consider the function displayed on the graph below.

according to the model, what will be the vo2 max of an athlete when they retire at the age of 38?
vo2 max = 50.8
3 well on track!
8c according to the model, at what age do athletes reach their maximum vo2 max?
age =

Explanation:

Step1: Analyze the graph

The graph is a parabola (quadratic function). The maximum point (vertex) of the parabola gives the age at which the VO2 max is maximum.

Step2: Locate the vertex

Looking at the graph, the x - coordinate (age) of the vertex (highest point) is 30.

Answer:

30
