Answer:
(1)
type-A:
type-B:
(2)
Step-by-step explanation:
We are given
type-A:
type-B:
(1)
At initial means t=0
For type-A:
we can plug t=0
For type-B:
we can plug t=0
(2)
we can set f(t)=g(t)
and then we can solve for t
we can draw graph of f(t) and g(t)
and then we can find intersection point
so, we got
Yes it can be divided 300 times
The leftmost line segment has a domain of -4 ≤ x < -1, or [-4, 1).
The central line segment has a domain of -1 ≤ x ≤ 2, or [-1, 2].
The rightmost line segment has a domain of 2 < x ≤ 5, or (2, 5].
Overall, this function has a domain of
[-4, 1) U [-1, 2] U (2, 5]
(where U means "union" in the set-theoretic notion)
But this also simplifies to the interval [-4, 5].
These correspond to the <u>first</u> and <u>last</u> choices.
Domain is on the y intercept. The answer would be B
