Question

Given the equation y=2^x, predict the equation for the graph that has been reflected in the y-axis. Given a vertical stretch by a factor of 5, translated 2 units right and 5 units down

Answer 1

y = 2^(-x) for negative x

stretch up by 5
y = 5 * 2^(-x)
go five right
y = 5 *2^(-x-1)
y = -5 + 5 * 2^-(x+1)
