Assuming that the x is not part of the ^-1 the range would be
[0,π/2) U (π/2,<span>π]</span>
We have

of 252 people who have a personalized black disc
Number of people who would have personalized flying disc =

people
Then we work out the number of people who like to play disc golf:

people
So we have 15 people who like to play disc golf and have personalised black disc.

the answer for the problem in the pic is A i think
Answer:
for the line to have a constant slope, the difference of every y- ordinate with the last ordinate has to be equal
to check this, we will use the following formula
y4 - y3 = y2 - y1
if both the LHS and the RHS are equal, the slope is constant and is irregular otherwise
5 - 8 = 7 - 3
-3 = 4
LHS ≠ RHS
Since LHS is not equal to RHS, the slope is NOT constant and hence keeps increasing or decreasing irregularly
Therefore, option 4 (Not a line) is correct
