Answer:
Given: piece wise function-
f(x) = x + 3 for x < 0 and f(x) = 2x for x ≥ 0
First part of the function does not include x = 0.
In slope-intercept form,
slope(m) = 1
y-intercept = (0,3).
So, the conditions are shown in graphs 1 and 3.
Now, the second part of the function equation passes through origin as the equation is f(x) = 2x.
Correct choice - [B]
Note: See picture of graph attached.

Answer:
Mark needs 110 ft. fencing to surround all 4 gardens.
Step-by-step explanation:
Mark wants to fence 4 rectangular gardens. So we calculate the perimeter of the each garden by this formula
P = 2(L) + 2(W)
Total Length of the garden =
=
Length = 18.5 feet
Total width of the garden =
=
Width = 9.0 feet
Perimeter of the garden = 18.5 + 9 = 27.5 feet
Mark wants to fence 4 garden
Therefore, 27.5 × 4 = 110 feet.
Mark needs 110 ft. fencing to surround all 4 gardens.
