Step-by-step explanation:
Consider the provided information.
Student on the cross-country team runs 30 minutes a day as a part of her training,
30 minutes = 0.5 hours
As we know
Let the distance she runs in miles, is represented by D, and her running speed, in miles per hour is represented by S.
Therefore, the required equation is:
Part (A) At a constant speed of 4 miles per hour for the entire 30 minutes.
Substitute S=4 in above equation.
Hence, the required equation is
Answer:
Use the appropriate entry method for piecewise functions for the graphing calculator of interest.
Step-by-step explanation:
For Desmos, the entry looks like ...
f(x) = {x ≤ 2: -2x-1,-x+4}
_____
For a TI-84 calculator, the entry may look like ...
Y₁ = (-2X–1)(X≤2) + (-X+4)(X>2)
The symbols ≤ and > come from the TEST menu, which is the (2nd) shift of the MATH key.
Note that the function is the sum of the pieces, each piece multiplied by a test. For something like 0≤x<2, the multiplier would be a pair of tests:
... (0≤X)(X<2)
