Question

What is the effect on the graph of the function f(x)=x when f(x) is replaced with -1/2f(x)?

Answer 1

The line will change its slope by a factor of -2 (line will now "point down" with twice the original steepness)

Explanation:

f(x) = x | replace f(x) --> (-1/2)f(x)

(-1/2)f(x) = x

f(x) = -2x
