C) y=7.
If it passes through the point (5,7) and is perpendicular to x=4, the line must be y=7.
15:11,this is right answer
Answer:
C) Horizontal compression
Step-by-step explanation:
Since, if y = f(x) is a function,
Then y = a f(x) gives a vertical stretch if a > 1 and gives a vertical compression if 0 < a < 1.
Also, y = f(bx) gives a horizontal stretch when 0 < b < 1 and gives a horizontal compression if b > 1.
Here,
The given parent function is,
f(x) = 2x
And, 3 > 1
Thus, by the above statements,
f(3x) will give a horizontal compression.
Hence, Option C is correct.
