When horizontally stretching a function by a factor of two, what happens to the slope?

• It doubles

• It remains the same

• It halves

• It becomes negative

In horizontal stretching, which part of the function is affected?

• Neither X nor Y portions

• Both X and Y portions

• The X portion

• The Y portion

What is the new function G(x) when the original function f(x) = 3x - 2 is horizontally stretched by a factor of two?
