What is the value of the expression-2(-3+-1)

-8

Step-by-step explanation:

Finding the value of an expressionmake use of the BODMAS rule

B- brackets

O - of

D- division

M- multiplication

A-addition

S- subtraction

solve what is in brackets first .

this is :

-3 + -1

= -4

now multiply by the value outside he brackets

-4 * 2

= -8

the value of the expression is -8

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
