Question

Given that (-3,-4) is on the graph of f(x) find the corresponding point for the function f(-3/4x)

Answer 1

Answer: (4,-4)

=======================================

Work Shown:

Set the expression (-3/4)x equal to the x coordinate of the given point, which is -3. Then solve for x

(-3/4)x = -3
-3x = -3*4
-3x = -12
x = -12/(-3)
x = 4
This is the new x coordinate of the answer. The y coordinate stays the same.
