In the same way that other functions can be combined, a series of transformations can be combined into a single function. for example, this statement for the function s shows one way to represent the rotation of a point 270° counterclockwise about the origin followed by a translation 3 units to the left and 1 unit up: s(270, o)/< -3,1> (x, y) = (y – 3, -x + 1).
write a function to represent each series of transformations:
-rotation of 90 degrees counterclockwise about the origin, point o, then a reflection across the x-axis
-reflection across the y-axis, then a translation a units to the right and b units up
-translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection across the y-axis

Someone answer this asap for gabriella uses the current exchange rate to write the function, h(x), where x is the number of u. s. dollars and h(x) is the number of euros, the european union currency. she checks the rate and finds that h(100) = 7.5. which statement best describes what h(100) = 75 signifies? a. gabriella averages 7.5 u. s. dollars for every 100 euros. b. gabriella averages 100 u. s. dollars for every 25 euros. c. gabriella can exchange 75 u. s. dollars for 100 euros. d. gabriella can exchange 100 u. s. dollars for 75 euros.
