Question 4 • Precalculus

Which transformations to the graph of j times x would result in the graph of j times 4 x minus 27 ?

Answer
A
horizontal compression by a factor of 1 fourth , and a translation 27 units down
B
horizontal stretch by a factor of 4 , and a translation 27 units right

Explanation

In j(4x), the input x is multiplied by 4, so the graph is compressed horizontally by a factor of 1/4. The −27 outside the function shifts the graph 27 units down, matching choice A.
