PLEASE SOMEONE HELPPP Write the transformation form of the equation for the cosine function that has been compressed vertically by a factor of 1/2, stretched horizontally by a factor of 4, and shifted down 1 unit

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h
