Question

The equation f(x)=5x−−√3+2.6
is transformed to f(6x)=5(6x)−−−−−√3+2.6
. Identify the value of k. Does the graph show a stretch or a compression?(1 point)

6; stretch

6x
; compression

4x
; stretch

6; compression

Answer 1

k = 6; compression.

Reason: replacing x with 6x (k = 6 > 1) produces a horizontal compression by factor 1/6.
