Answer 1

Answer:

A. The y-intercepts are the same.

B.  function $3f(x)$ has a greater rate of change.

Step-by-step explanation:

We have $f(x)=x$

Let $g(x)=3*f(x)$

Then $g(x)=3x$

The y-intercept of  $f(x)=x$ is 0

The y-intercept of   $g(x)=3x$ is also 0

Therefore the y-intercepts are the same.

The rate of change of  $f(x)=x$ is 1

The rate of change of $g(x)=3x$  is 3

Hence the function $3f(x)$ has a greater rate of change.

The two functions are not parallel because they have different rate of change.

f(x) translated 3 units up is f(x)+3. This is not the same as 3x
