Answer:
Step-by-step explanation:
<u>Piecewise Function</u>
The given function has a point where its behavior changes. At the left side of x=3 the function is
While at the right side the function is
We need to find the range of h, i.e. the values h takes when x moves along its domain. Let's analyze what values takes h when x decreases without limit.
When x=3
When x increses without limit
As shown, the values of h run from to 5, i.e.
Or, equivalently
Answer:
x= 3s -8
3 times Sarah's age is 3s hence the expression is as shown
The given graph is parabola graph with vertex at the point (2.0,24) and branches of the parabola go in a negative direction of y-axis.
As known parabola is symmetric about her <span>axis of symmetry and in this case the symmetry axis has equation t=2.0 (vertical line). Thus, the height of the javelin above the ground is symmetric about the line t=2.0.
</span><span>
</span><span>From the graph you can see that the first time when javelin is 20 feet above the ground is when t=1.0 and the second time is t=3.0 (to determine this you should draw horizontal line through point (0,20) and consider two points of intersection (1.0,20), (3.0,20) between parabola and horizontal line).
