Answer:

he total time is 4 seconds. The elevator descends 10 feet each second so the total is:

4seconds x -10 feet/sec = -40 feet

The total change in elevation is -40 feet. You need the negative sign because the elevator is moving downward. Hope this helps!

For the function defined by:

Eva8 [605]

The first function is represented by the green line, while the second is represented by the orange line

<h3>What are piecewise functions?</h3>

Piecewise functions are functions that have at least 2 sub functions, each of which have different intervals

The function is defined by

$f(x) = \left \{ {{x^2,\ x\le1} \atop {2x + 1,\ x > 1}} \right.$

<h3>(a) Graph the first function</h3>

The first function in f(x) is defined by

$f(x) = x^2, \ x \le 1$

See attachment for the graph of the first function

<h3>(b) Graph the second function</h3>

The second function in f(x) is defined by

$f(x) = 2x + 1, \ x > 1$

See attachment for the graph of the second function
