Answer:
-2
Step-by-step explanation:
When you're looking for f(3), you want the y-value that corresponds to the x-value of 3. Find it by locating 3 on the x-axis. Then follow the vertical grid line to the point where the function value is shown. From there, identify the y-coordinate of that point. That y-coordinate is f(3).
f(3) = -2
__
The open dots at the ends of the curves at x=3 mean the function is not defined at those points: (3, 1) or (3, -9). The solid dot at (3, -2) tells you the function value at x=3 is -2.

Answer:
y = 1/2x -3
Step-by-step explanation:
We can use the slope intercept form the equation for a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x +b
Substitute the point into the equation
-4 = 1/2(-2) +b
-4 = -1+b
Add 1 to each side
-4 +1 = -1 +1+b
-3 = b
Writing the equation
y = 1/2x -3
I did that equation on the side and I got 442, I hope this helps
For this case what you must do is convert the inequations into equations. Then graph both lines and see what is the set of possible solutions (if any).
The shaded region in this case represents the solution set of the inequation system.
The answer for this case is
False: There are solutions
