Question

Suppose the function P (t) gives the pulse rate of a gymnast at various points in time during 10 sessions. Select an appropriate domain for this function. Assume that the gymnast complete the 10 sessions in 95 minutes.
A) The domain is all rational numbers x such that 0≤x≤95
B)The domain is all rational numbers x such that 0≥x≥95
C)The domain is all integers x such that 0≤x≤95
D)The domain is all integers x such that 0≥x≥95

Answer 1

Answer:

C

Step-by-step explanation:

When we talk of domain, we are referring to the values we have on the x axis

By considering the range of values we have on the x-axis, we have the domain we want

We have the gymnast complete the sessions in 95 seconds.

This means that the highest point on the x-axis is 95 seconds

But how do we measure time? we do this in form of integers

So the correct domain will be all

integers between 0 and 95

which can be represented as 0≤x≤95
