Plzzz help Is the graph in the picture a function or not a function?
Please explain.

THis is a function.

Step-by-step explanation:

If you draw a straight line vertically, it won't intersect more than one point of the line. This is called the vertical line test, and if the line you drew passes the line on the graph more than once, its not a function.

Yw, brainliest, and don't plagiarize, they'll catch you.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
