The final equation after the transformation is g(x) = -3 [x]
How to write the expression
The parent function is given as
g(x) = [x]
a vertical stretch by a factor of 3, will result to
g(x) = 3 [x]
a reflection in the x-axis, will result to
g(x) = -3 [x]
complete question
Write an equation that represents a vertical stretch by a factor of 3 and a reflection in the x-axis of the graph of g(x)=[x].
