What is the equation of the graph below?

B

Step-by-step explanation:

the standard form of a sine wave is

y = asinbx + c

where a is the amplitude , period = and c is the vertical shift

a = = = 1

period =

b = = 3 , c = 0

hence y = sin 3x is the equation of graph

B

Step-by-step explanation:

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
