A. When compared to f(x) = 2x, g(x) will be reflected over the x-axis.
A True B False
B. When compared to f(x) = 2x, g(x) will have a vertical stretch of 3.
A True B False
C. When compared to f(x) = 2x, g(x) will be translated right 1 unit and up 1 unit.
A True B False

Respuesta :

we are given

[tex]g(x)=-3f(x+1)-1[/tex]

we will verify each options

option-A:

we can see that f is multiplied by -1

so, it is reflected about x-axis

so, this is TRUE

option-B:

We can see that

3 is multiplied with f

so, it is stretched vertically by 3  units

so, this is TRUE

option-C:

we are given

x+1 inside f

so, it will be  translated f(x) to left side by 1 unit

so, this is FALSE
