First, set 2x+7 equal to 3x-7 since they are the same angle due to the parallel lines.

2x+7=3x-7
x=14

Then, since 2x+7 and 12y+1 equals 180, put it together to find y:

(2x+7)+(12y+1)=180
(2(14)+7)+(12y+1)=180
12y+1=145
12y=144
y=12

So, x=14 and y=12. Your answer should be C!

The function f(x)=-3 cos(2x+pi/4) has ___

morpeh [17]

The domain will be ( 0, ∞) and the range of the function F(x) = -3Cos[2x+ $\dfrac{\pi}{4}$ ] will be [ $\dfrac{-\pi}{8}$ , -3 ] and [ $\dfrac{3\pi}{8}$ ,3].

<h3>What are domain and range?</h3>

Range and Domain. The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

The range of the function we can see from the graph of the function will be from [ $\dfrac{-\pi}{8}$ , -3 ] and [ $\dfrac{3\pi}{8}$ ,3]

The domain of the function will be all the values of the real numbers for the function ranges from ( 0, ∞ ).

Therefore the domain will be ( 0, ∞) and the range of the function F(x) = -3Cos[2x+ $\dfrac{\pi}{4}$ ] will be [ $\dfrac{-\pi}{8}$ , -3 ] and [ $\dfrac{3\pi}{8}$ ,3].

The complete question is given below:-

what is the domain and range of the function

F(x) = -3Cos[2x+ $\dfrac{\pi}{4}$ ] .
