The function has a local minima at ( 20 , -7 )
What is a Function ?
Function is a mathematical statement formed when two algebraic expression are equated by an equal sign.
The expression given is
y = -2 +5sin ( (π/12) (x-2))
the minima of the given expression will be when
the sine term = -1
as the lowest value sin can have is -1
y = -2 +5 * (-1)
y = -7
The sin ( (π/12) (x-2)) = -1
(π/12) (x-2) = 3π /2
On solving this
x = 20
Therefore the function has a local minima at ( 20 , -7 )
It can also be confirmed form the graph attached with the answer.
