The graph here shows transformations of the graph of f(x) = 2x. What is the equation for the transformation?
Consider the graph of the transformation of the function f(x) = 2x as shown.
Consider the transformation of the function shown in the graph be f(x) = 2x+c + d.
Since, the horizontal asymptote of the graph is –2
Therefore,
d = -2
Since, the graph passes through the point (2, 0)
Therefore,
0 = 22+c – 2
2 = 22+c
This implies that
2 + c = 1
c = -1
Hence, the transformation of f(x) = 2x shown in the graph is f(x) = 2x-1 – 2.
Hence, the transformation of f(x) = 2x shown in the graph is f(x) = 2x-1 – 2.
