Which graph represents the piecewise-defined function?

y=⎧⎩⎨⎪⎪−4   if  x≤−30   if  x=23    if  x> 2

it can be a pain when nobody helps... ur top right is correct

Step-by-step explanation:

heres a screenshot ..

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
