If f(x)=7^x is horizontally stretched by a factor of 5, moved up 3 units, and reflected across the x-axis, which of the following is the new expression of f(x)?

Answer 1

The new expression of f(x) after being horizontally stretched by a factor of 5, moved up 3 units, and reflected across the x-axis is:

g(x) = -7^(5x) + 3
