Activity: Imagine that you have a shrink ray. If you set the sizer of your shrink ray to 1/3 and zap yourself, how tall will you be in inches? What if
you set it to 2/5 instead? 3/7?

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
