(Acellus Piece-wise defined functions) Using the function below, what is f(-1)?

2x-1 if x is less than or equal to 0

f(x)={

4x+3 if x is greater than 0

f(-1)= ?

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
