Question

Let f(x) = 9x

Which statement describes the transformation of the graph of f(x) to the graph of 2f(x) - 5?

Question 5 options:

Vertically stretch by a factor of 2 and translate down 5 units.


Vertically stretch by a factor of -5 and translate down 2 units.


Reflect the graph of f(x) over the x-axis and translate down 5 units.


Reflect the graph of f(x) over the x-axis and translate up 5 units.

Answer 1

Vertically stretch by a factor of 2 and translate down 5 units.

Answer 2

that is A.
whenever the the number with which we are multiplying is greater than one, the graph stretches here we have multiplied fx by 2 so the graph will stretch and as we are subtracting 5 from it. it will get down by 5 units.
