The function f(x) is less than 0 at x < -1.8
<h3>How to analyze the graph?</h3>
The missing graph is added as an attachment
The interval where f(x) < 0 are the intervals where the y value of the function is less than 0.
This in other words, represent the negative y-axis
From the attached graph, the function f(x) is less than 0 at x < -1.8.
This extends till x = infinity
Hence, the function f(x) is less than 0 at x < -1.8

Use the Pythagorean theorem to find X
A² + B² = C²
X² + 4² = 5²
X² = 5² - 4²
X² = 25 - 16
X² = 9
.: X = 3
Answer:
y=2x+2
Step-by-step explanation:
Remember that parallel lines have equal slopes. We can solve this using point slope form which is 
Plug in the point (0,2) into the equation:
y-2=m(x-0)
Also plug in the slope which is the same as line EF (m=2)
y-2=2(x-0)
Simplify:
y-2=2x
Add 2 to both sides:
y=2x+2
Answer:
Simplified expression: 4b + 4c - 5
Perimeter: 27
Step-by-step explanation:
To find the perimeter, we add the lengths of the sides of the quadrilateral, so 2b + 4b - 5 + 3c - 2b + c, which simplifies to 4b + 4c - 5.
Plugging in b = 5 an c = 3, we get 4*5 + 4*3 - 5, which gets us 27.
