Sagot :
The correct option C which is true for the given form of the sine curve f(x) = –2sin(x) – 3.
What is the range of the function?
The range of a function is defined as the set of all the possible output values that are valid for the given function.
The general form of the sine curve is given as
f(x) = –2sin(x) – 3
A.
Since this curve's A is -2, its amplitude is 2 and its range is from -2 to 2. but since the D value is -3, it shifts vertically 3 units down making the range from -1 to -5. Choice A is not true.
B.
This graph is the graph of shifted 3 units down since D is negative. This choice isn't true.
C.
Because of the (minus) sign in front of the function, the function is reflected on the x-axis, but the amplitude doesn't change. Since A value is 2, the amplitude is 2. This is true.
D.
The period depends on the B value. Here, the B value is 1, so the period is normal as the parent function of a sine curve, which is, not. So this is not correct.
Therefore, C is the correct answer.
