Please help me understand the question

The major arc DGF and the minor arc FD both make up the circle, so their measures should add to 360°.

(arc DGF) + 153° = 360°

arc DGF = 207°

9514 1404 393

  C.  207°

Step-by-step explanation:

Points D and F divide the circle into two arcs. The short arc is referred to by its end point: arc DF. The long arc has the same end points, so is referred to using a third point somewhere on the arc. That point is G.

Together, arcs DF and DGF make the complete circle, or 360°. The measure of long arc DGF can be found from that fact:

  DF +DGF = 360°

  153° +DGF = 360° . . . . substitute the given value for arc DF

  DGF = 360° - 153°

  arc DGF = 207°

Additional comment

The tangents and external angle are completely irrelevant to the question asked by this problem.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
