Use the graphs of f and g to solve Exercises 87, 88, and 89.

Mathematics
1 answer:
Nadya [2.5K]3 years ago
4 0

Answers and explanations:

87. The domain of added functions includes the restrictions of both. So the range of the added function in this question is [-4, 3]

88. When finding the domain of a divided function we do the same as adding, but with an extra rule: g can't equal zero. So for this question the domain is (-4, 3)

89. To graph f + g you add the y-values for each x-value. I added a picture to help explain this one!

Find all solutions in the interval [0, 2π) sin2x + sin x = 0
Molodets [167]
Sin 2 x + sin x = 0
( sin 2 x = 2 sin x cos x )
2 sin x cos x + sin x  = 0
sin x ( 2 cos x + 1 ) = 0
sin x = 0 
x 1 = 0
x 2 = π 
or: 2 cos x + 1 = 0
2 cos x = - 1
cos x = -1/2
x 3 = 2π/3
x 4 = 4π/3
