Which of the following are equivalent to the function y = -3sin x + 2? check all that apply.

(A) and (D)

Step-by-step explanation:

The given function is :

Now, A.

⇒(because -sinx=sin(-x))

which matches with the given function, thus A is the correct option.

B.

which does not matches with the given function, thus B is not the correct option.

C.

On solving, we get

which does not matches with the given function, thus C is not the correct option.

D.

On solving, we get

which matches with the given function, thus D is the correct option.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
