We need to find an inequality that represents the possible landing or take of conditions of an aircraft, the required graph and one case where the inequality will be tested.
The required inequality is .
The graph represents the allowable temperature range in which the aircraft can takeoff or land.
The pilot could not have taken off on June 1990, the temperature in Phoenix, Arizona.
Let the temperature be denoted by
The temperature cannot be at or below , so
The temperature cannot be at or above , so
The inequality will be .
In the graph it can be seen that all points between -40 and 118 falls in the shaded region but it will exclude the points -40 and 118.
The graph represents the allowable temperature range in which the aircraft can takeoff or land.
The temperature in June 1990 in Phoenix, Arizona was which is more than
.
Hence, the pilot could not have taken off on this day.

Using the definition of the Vertical shifts of graphs of the function :
"Suppose c>0,
To graph y=f(x)+c, shift the graph of y=f(x) upward c units.
To graph y=f(x)-c, shift the graph of y=f(x) downward c units"
Again we recall the definition of Horizontal shifts of graphs:
" suppose c>0,
the graph y=f(x-c), shift the graph of y=f(x) to the right by c units
the graph y=f(x+c), shift the graph of y=f(x) to the left by c units. "
consider is the parent function.
shifts the graph
upward by 8 units
shifts the graph
downward by 8 units
shifts the graph
left by 8 units
shifts the graph
right by 8 units.
