Question in the picture!

If f(x) = 3x-2 and g(x) =2x+1 find (f-g)(x)

What is the scale factor of axyz to auvw?

The graph of the function f(x) = (x + 2)(x + 6) is shown below. which statement about the function is true? the function is positive for all real values of x where x > –4. the function is negative for all real values of x where –6 < x < –2. the function is positive for all real values of x where x < –6 or x > –3. the function is negative for all real values of x where x < –2.
