The -3 in f(-3) is the X coordinate, so you need to find where the line is on the Y coordinate at that point.
The line is at Y = -9
The addition of +7 influences the y values of the graph. Since it is positive, the graph of y=IxI would be moved 7 units upwards.
Hope I helped :)
Answer:
3. C≈31.42
4.C≈94.25
Step-by-step explanation:
10 ÷ 2 =5
C=2πr
c=2 (3.14) 5
c= 2(3.14)15
