Answer:
The range is
The graph in the attached figure
Step-by-step explanation:
we have
The domain is the interval ----> given problem
Remember that
The domain of a function is the set of all possible values of x
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
To find out the range of the function , find the value of y for each value of x
so
For x=-2 ----> y=-2-7=-9
For x=-1 ----> y=-1-7=-8
For x=0 ----> y=0-7=-7
For x=1 ----> y=1-7=-6
For x=2 ----> y=2-7=-5
therefore
The range is
The graph in the attached figure
Draw the triangle as shown in the figure below.
a=5.3, b=7, c=4.
The smallest angle is ∠C because it is opposite the shortest length of 4.
From the Law of Cosines,
c² = a² + b² - 2ab cosC
or
cos C = (a² + b² - c²)/(2ab)
= (5.3² + 7² - 4²)/(2*5.3*7)
= 0.823
∠C = arcos(0.823) = 34.58°
This answer agrees reasonably with 34.38°
