What is the range of y = –5sin(x)? all real numbers Negative 5 less-than-or-equal-to y less-than-or-equal-to 5 all real numbers
Paraphin [41]

Answer:

The range of given function is

[-5,5]    

Step-by-step explanation:

We are given the function:

y = -5\sin(x)

We have to find the range of the given function.

Range of function

  • Range is the collection of all possible values of y for the domain of function.

Range of basic sine function is

-1\leq \sin(x) \leq 1

Multiplying the range by -5

5\geq -5\sin(x) \geq -5

Thus, the range of given function is

-5\leq -5\sin(x) \leq 5

-5\leq y\leq 5

Thus, the range of given function is

[-5,5]

The attached image shows the graph for the given function.
